    What did the others do? Recommending by Visualising Fellow Travellers2003In: ERCIM News, ISSN 0926-4981, E-ISSN 1564-0094, no 53Article in journal (Refereed)
    Abstract [en]

    A problem when making recommendations based on the aggregated behavior of many users (collaborative recommendation) is to explain the rationale behind the recommendation. Our work investigates the alternative approach of visualizing the collaborative data, leaving it to the user to decide on a course of action, i.e. create the recommendation. A prototype system was built and evaluated in a joint project with the international transport and travel service company Stena Line. A user study showed that displaying statistics on other traveler’s ticket bookings indeed functioned as recommendations.

    Designing a Mobile Social Service for a Mall: User Experiences of Kista Galleria2003Report (Other academic)
    Abstract [en]

    A study was performed to investigate a domain for a mobile and social service, where a web of social trails is overlaid over a physical space. Using a method inspired by work of the city planner Kevin Lynch, 20 subjects were interviewed about their experiences, activities, movements and habits related to a specific shopping mall. Design implications for the service were drawn from subjects’ sketches of the area, lists of places important to them, and their daily routes through the mall as drawn on a standardized map. Three user groups were identified based on the amount of activities and time spent in the mall: dwellers, shoppers and exploiters. User sketches indicated that traditional maps are not an optimal means for visualising the mall in the service. Finally, the way subjects grouped, labelled and defined places and objects in the mall provided valuable input to the design of the service interface.

    Social positioning: Designing the Seams between Social, Physical and Digital Space2005Conference paper (Refereed)
    Abstract [en]

    Mobile settings are not only physically and digitally mediated; they are also inhabited by people - a social space. We argue that careful design exposing the connections, gaps, overlays and mismatches within and between physical, digital and social space allow for a better understanding and thereby mastering of the resulting combined space. Two concepts are explored in MobiTip, a social mobile service for exchanging opinions among peers: intramedia seams concerning network coverage and position technology, and intermedia seams between digitally transmitted tips and the physical, social context surrounding the user. We introduce social positioning as an alternative and complement to the current strive for seamless connectedness and exact positioning in physical space.

    Capturing TV user behaviour in fictional character descriptions2008Report (Other academic)
    Abstract [en]

    This work is part of the On-demand IPTV project, conducted by Acreo and SICS with financing from Vinnova and active support from an industrial consortium. The main goal of the project is to study the demands on cost-effective, scalable video-on-demand networks that can deliver video with high-quality with minor quality degradations in the transmission. An important issue in understanding this situation is to explore future user behaviour (and the resulting traffic patterns) when user can choose a mix of broadcast TV and a large number of on-demand channels and services. This paper reports on the first steps to develop an understanding of IPTV user behaviour by investigating the current situation using archetypical, fictional character descriptions often referred to as personas. This is an intermediate version; the final version will be the result of Task 4.1: User requirements analysis, part of WP 4: User needs and behaviour.

    How to choose and how to watch: an on-demand perspective on current TV practices2010Report (Other academic)
    Abstract [en]

    In Sweden, digital TV services have until very recently not been accessible to most people through the TV set. At the same time, TV channels offer more and more content on the web and the majority of the population has access to high-speed internet connections. A web survey aimed at investigating attitudes and behavior related to on-demand TV was distributed in December 2008 to 52 households in an experimental, open (operator neutral) access network in Sweden. Questions were posed on TV arrangements, habits and attitudes; social aspects of TV watching; watching film or TV on-demand; and watching film or TV using the computer. Complementary interviews were also performed with participants that were not part of the experimental environment. Results show that participants in the studies understood and felt a need for time-shift and on-demand TV services: time-shift needs for re-scheduling, catch-up and repeats were expressed as well as on-demand needs for movies and for accessing otherwise unavailable TV content. Support for on-demand TV could also be found in that subjects reported little need for viewing TV content according to a broadcast schedule, with the main exception of news, sports events and other live broadcasts.

    Interactive adaptation of Intranet newsletters1997Conference paper (Refereed)
    Abstract [en]

    We propose a new approach to edit and adapt information from the web. The advantage of the proposed approach, edited adaptive hypermedia, is that it combines human expertise with machine intelligence. A user-adaptive WWW browser communicates with an information broker environment, in which information can be retrieved and structured to fit the target user group or groups. We exemplify the approach with an application at a Swedish company: newsletter distribution on an Intranet. The information is adapted at the reader side, based on annotations on each article from the newsletters.

    Abstract [en]

    ``Team Sweden'' is the Swedish national team that entered the Sony legged robot league at the RoboCup '99 and RoboCup 2000 competitions. We had two main requirements in mind when preparing our entries: 1. The entry should effectively address the specific challenges present in this domain; in particular, it should be able to tolerate errors and imprecision in perception and execution; and 2. it should illustrate our research in autonomous robotics, by incorporating general techniques that can be reused in different robots and environments. While the first requirement could have been met by writing some ad hoc competition software, the second one led us to develop principled solutions that drew upon our current research in robotics, and that pushed it further ahead.

    Permutations as a means to encode order in word space2008Conference paper (Refereed)
    Abstract [en]

    We show that sequence information can be encoded into high-dimensional fixed-width vectors using permutations of coordinates. Computational models of language often represent words with high-dimensional semantic vectors compiled from word-use statistics. A word's semantic vector usually encodes the contexts in which the word appears in a large body of text but ignores word order. However, word order often signals a word's grammatical role in a sentence and thus tells of the word's meaning. Jones and Mewhort (2007) show that word order can be included in the semantic vectors using holographic reduced representation and convolution. We show here that the order information can be captured also by permuting of vector coordinates, thus providing a general and computationally light alternative to convolution.

    Health Data: Representation and (In)visibility2015Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Health data requires context to be understood. I show how, by examining two areas: self-surveillance, with a focus on representation of bodily data, and mass-surveillance, with a focus on representing populations. I critically explore how Information and Communication Technology (ICT) can be made to represent individuals and populations, and identify implications of such representations. My contributions are: (i) the design of a self-tracking stress management system, (ii) the design of a mass-surveillance system based on mobile phone data, (iii) an empirical study exploring how users of a fitness tracker make sense of their generated data, (iv) an analysis of the discourse of designers of a syndrome surveillance system, (v) a critical analysis of the design process of a mass-surveillance system, and (vi) an analysis of the historicity of the concepts and decisions taken during the design of a stress management system. I show that producing health data, and subsequently the technological characteristics of algorithms that produce them depend on factors present in the ICT design process. These factors determine how data is made to represent individuals and populations in ways that may selectively make invisible parts of the population, determinants of health, or individual conception of self and wellbeing. In addition, I show that the work of producing data does not stop with the work of the engineers who produce ICT-based systems: maintenance is constantly required.

    Considering Pigeons for Carrying Delay Tolerant Networking based Internet traffic in Developing Countries2012In: The Electronic Journal of Information Systems in Developing Countries, E-ISSN 1681-4835, Vol. 54, p. 1-19Article in journal (Refereed)
    Abstract [en]

    There are many regions in the developing world that suffer from poor infrastructure and lack of connection to the Internet and Public Switched Telephone Networks (PSTN). Delay Tolerant Networking (DTN) is a technology that has been advocated for providing store-and-forward network connectivity in these regions over the past few years. DTN often relies on human mobility in one form or another to support transportation of DTN data. This presents a socio-technical problem related to organizing how the data should be transported. In some situations the demand for DTN traffic can exceed that which is possible to support with human mobility, so alternative mechanisms are needed. In this paper we propose using live carrier pigeons (columba livia) to transport DTN data. Carrier pigeons have been used for transporting packets of information for a long time, but have not yet been seriously considered for transporting DTN traffic. We provide arguements that this mode of DTN data transport provides promise, and should receive attention from research and development projects. We provide an overview of pigeon characteristics to analyze the feasibility of using them for data transport, and present simulations of a DTN network that utilizes pigeon transport in order to provide an initial investigation into expected performance characteristics.

    Design and Implementation of the Node Identity Internetworking Architecture2010In: Computer Networks, ISSN 1389-1286, E-ISSN 1872-7069, Vol. 54, p. 1142-1154Article in journal (Refereed)
    Abstract [en]

    The Internet Protocol (IP) has been proven very flexible, being able to accommodate all kinds of link technologies and supporting a broad range of applications. The basic principles of the original Internet architecture include end-to-end addressing, global routeability and a single namespace of IP addresses that unintentionally serves both as locators and host identifiers. The commercial success and widespread use of the Internet have lead to new requirements, which include Internetworking over business boundaries, mobility and multi-homing in an untrusted environment. Our approach to satisfy these new requirements is to introduce a new Internetworking layer, the node identity layer. Such a layer runs on top of the different versions of IP, but could also run directly on top of other kinds of network technologies, such as MPLS and 2G/3G PDP contexts. This approach enables connectivity across different communication technologies, supports mobility, multi-homing, and security from ground up. This paper describes the Node Identity Architecture in detail and discusses the experiences from implementing and running a prototype.

    Heterogeneous scheduling and rostering2001In: ALP Newsletter for Logic ProgrammingArticle in journal (Refereed)
    Abstract [en]

    We have designed and implemented a distributed model for planning and scheduling of transports in a railway company which is usable also for other production planning problems. Our model emphasises the use of an agent for the co-ordination of distinct sub-problems occurring in railway scheduling such as for instance the allocation of track resources to transports, the allocation of vehicles to transports, and the allocation of staff to perform the transportation tasks. Using constraints as the key technology, we are interested in finding interfacing principles to combine several solvers to allow users, for instance reasoning agents, to have a uniform view of the combined constraint store of heterogeneous solvers. Abstraction of constraint stores is an important technique used to enable translations between heterogeneous solvers and to improve performance of the overall combined problem of producing a railway schedule. By using abstractions of relevant representations we achieve a hierarchical system which by focusing attention on different levels of abstraction can achieve an acceptable solution faster than previous techniques.

    Probabilistic Fault Management in Networked Systems2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Technical advances in network communication systems (e.g. radio access networks) combined with evolving concepts based on virtualization (e.g. clouds), require new management algorithms in order to handle the increasing complexity in the network behavior and variability in the network environment. Current network management operations are primarily centralized and deterministic, and are carried out via automated scripts and manual interventions, which work for mid-sized and fairly static networks. The next generation of communication networks and systems will be of significantly larger size and complexity, and will require scalable and autonomous management algorithms in order to meet operational requirements on reliability, failure resilience, and resource-efficiency. A promising approach to address these challenges includes the development of probabilistic management algorithms, following three main design goals. The first goal relates to all aspects of scalability, ranging from efficient usage of network resources to computational efficiency. The second goal relates to adaptability in maintaining the models up-to-date for the purpose of accurately reflecting the network state. The third goal relates to reliability in the algorithm performance in the sense of improved performance predictability and simplified algorithm control. This thesis is about probabilistic approaches to fault management that follow the concepts of probabilistic network management (PNM). An overview of existing network management algorithms and methods in relation to PNM is provided. The concepts of PNM and the implications of employing PNMalgorithms are presented and discussed. Moreover, some of the practical differences of using a probabilistic fault detection algorithm compared to a deterministic method are investigated. Further, six probabilistic fault management algorithms that implement different aspects of PNM are presented. The algorithms are highly decentralized, adaptive and autonomous, and cover several problem areas, such as probabilistic fault detection and controllable detection performance; distributed and decentralized change detection in modeled link metrics; root-cause analysis in virtual overlays; event-correlation and pattern mining in data logs; and, probabilistic failure diagnosis. The probabilistic models (for a large part based on Bayesian parameter estimation) are memory-efficient and can be used and re-used for multiple purposes, such as performance monitoring, detection, and self-adjustment of the algorithm behavior.

    An initial approach to distributed adaptive fault-handling in networked systems2009Report (Other academic)
    Abstract [en]

    We present a distributed adaptive fault-handling algorithm applied in networked systems. The probabilistic approach that we use makes the proposed method capable of adaptively detect and localize network faults by the use of simple end-to-end test transactions. Our method operates in a fully distributed manner, such that each network element detects faults using locally extracted information as input. This allows for a fast autonomous adaption to local network conditions in real-time, with significantly reduced need for manual configuration of algorithm parameters. Initial results from a small synthetically generated network indicate that satisfactory algorithm performance can be achieved, with respect to the number of detected and localized faults, detection time and false alarm rate.

    Distributed detection of latency shifts in networks2009Report (Other academic)
    Abstract [en]

    We present the extension of a distributed adaptive fault-detection algorithm applied in networked systems. In previous work, we developed an approach to probabilistic detection of communication faults based on measured probe response delays and packet drops. The algorithm is here extended to detect network latency shifts and adapt to long-term changes of the expected probe response delay. Initial performance tests indicate that detected latency shifts and communication faults successfully can be localised to links and nodes. Further, the amount of network traffic produced by the algorithm scales linearly with the network size.

    Long-term adaptation and distributed detection of local network changes2010Conference paper (Refereed)
    Abstract [en]

    We present a statistical approach to distributed detection of local latency shifts in networked systems. For this purpose, response delay measurements are performed between neighbouring nodes via probing. The expected probe response delay on each connection is statistically modelled via parameter estimation. Adaptation to drifting delays is accounted for by the use of overlapping models, such that previous models are partially used as input to future models. Based on the symmetric Kullback-Leibler divergence metric, latency shifts can be detected by comparing the estimated parameters of the current and previous models. In order to reduce the number of detection alarms, thresholds for divergence and convergence are used. The method that we propose can be applied to many types of statistical distributions, and requires only constant memory compared to e.g., sliding window techniques and decay functions. Therefore, the method is applicable in various kinds of network equipment with limited capacity, such as sensor networks, mobile ad hoc networks etc. We have investigated the behaviour of the method for different model parameters. Further, we have tested the detection performance in network simulations, for both gradual and abrupt shifts in the probe response delay. The results indicate that over 90% of the shifts can be detected. Undetected shifts are mainly the effects of long convergence processes triggered by previous shifts. The overall performance depends on the characteristics of the shifts and the configuration of the model parameters.

    Performance Evaluation of a Distributed and Probabilistic Network Monitoring Approach2012Conference paper (Refereed)
    Abstract [en]

    We investigate the effects of employing a proba- bilistic fault detection approach relative the performance of a deterministic network monitoring method. The approach has its foundation in probabilistic network management, in which performance limits and thresholds are specified in terms of e.g. probabilities or belief values. When combined with adap- tive mechanisms, probabilistic approaches can potentially offer improved controllability, adaptivity and reliability, compared to deterministic monitoring methods. Results from synthetically generated and real network QoS measurements indicate that the probabilistic approach generally can perform at least as good as a deterministic algorithm, with a higher degree of predictable performance and resource-efficiency. Due to the stochastic nature of the algorithm, worse performance than expected is sometimes observed. Nevertheless, the results give additional support to some of the practical benefits expected in using probabilistic approaches for network management purposes.

    Towards Distributed and Adaptive Detection and Localisation of Network Faults2010Conference paper (Refereed)
    Abstract [en]

    We present a statistical probing-approach to distributed fault-detection in networked systems, based on autonomous configuration of algorithm parameters. Statistical modelling is used for detection and localisation of network faults. A detected fault is isolated to a node or link by collaborative fault-localisation. From local measurements obtained through probing between nodes, probe response delay and packet drop are modelled via parameter estimation for each link. Estimated model parameters are used for autonomous configuration of algorithm parameters, related to probe intervals and detection mechanisms. Expected fault-detection performance is formulated as a cost instead of specific parameter values, significantly reducing configuration efforts in a distributed system. The benefit offered by using our algorithm is fault-detection with increased certainty based on local measurements, compared to other methods not taking observed network conditions into account. We investigate the algorithm performance for varying user parameters and failure conditions. The simulation results indicate that more than 95 % of the generated faults can be detected with few false alarms. At least 80 % of the link faults and 65 % of the node faults are correctly localised. The performance can be improved by parameter adjustments and by using alternative paths for communication of algorithm control messages.

    Observing Software-defined Networks Using a Decentralized Link Monitoring Approach2015In: Proceedings of the 2015 1st IEEE Conference on Network Softwarization (NetSoft), 2015, 10, article id 7116137Conference paper (Refereed)
    Abstract [en]

    Scalable and automated monitoring processes for testing, debugging, and operation of VNFs and service-chains are crucial components towards achieving the aims of network softwarization - i.e., cheaper, faster, and shorter service deployment and network management processes. In this paper we present a decentralized monitoring approach aimed at supporting automated deployment and operation of VNFs and service-chains. The approach is inspired by network tomography and is designed to address observability limitations and scalability issues that arise from performing measurements from an SDN controller. From successive end-to-end measurements link metrics are derived via in-network parameter estimation with no need of forwarding raw measurements to the controller, which significantly reduces the measurement overhead compared to when monitoring individual links explicitly from an SDN controller.

    Resource management in radio access and IP-based core networks for IMT advanced and beyond2013In: Science China Information Sciences, ISSN 1674-733X, E-ISSN 1869-1919, Vol. 56, no 2, p. 169-184Article in journal (Refereed)
    Abstract [en]

    The increased capacity needs, primarily driven by content distribution, and the vision of Internet-of-Things with billions of connected devices pose radically new demands on future wireless and mobile systems. In general the increased diversity and scale result in complex resource management and optimization problems in both radio access networks and the wired core network infrastructure. We summarize results in this area from a collaborative Sino-Swedish project within IMT Advanced and Beyond, covering adaptive radio resource management, energy-aware routing, OpenFlow-based network virtualization, data center networking, and access network caching for TV on demand.

    Timetabling based on generalised cost2015Report (Other academic)
    Abstract [en]

    The liberalised railway market of today calls for new methods to plan the annual timetable. A conflict between two railway undertakings operating in the same market is hard to solve using the current method. Common price setting strategies such as auctions, framework agreements and spot markets may be of help. To administer a long term stability for an operator, framework agreements can be entered. These framework agreements should be valid for several years but still not consume too much capacity from other operators. In this report we propose a novel mathematical model calculating the benefit of subsidised traffic, based on the generalised cost of it’s timetable and optimisation models are developed. The calculated benefit is weighted against traffic from other operators, to provide a decision support for concluding the content of the framework agreements.

    Offloading Cellular Traffic with Opportunistic Networks: A Feasibility Study2015In: 2015 14th Annual Mediterranean Ad Hoc Networking Workshop (MED-HOC-NET), 2015, 17, article id 7173296Conference paper (Refereed)
    Abstract [en]

    The widespread diffusion of powerful mobile devices with diverse networking and multimedia capabilities, and the associated blossoming of content-centric multimedia services is contributing to the exponential increase of data traffic in cellular networks. Mobile data offloading is a promising technique to cope with these problems, which allows to deliver data originally targeted for cellular networks to complementary networking technologies. Among the various forms of mobile data offloading in this study we focus on offloading through opportunistic networks. Differently from previous studies in this field we evaluate the efficiency of opportunistic offloading schemes by using a real cellular traffic dataset collected in a large metropolitan area over a period of one month. We focus our analysis on video requests for popular video providers, and we evaluate the potential benefits of using an opportunistic data dissemination scheme to request this videos from local users instead of using the cellular network. As a benchmark, we compare the performance of such system with a simple caching mechanism. We show that a simple opportunistic offloading scheme can improve the performance of the caching system even if only 10% of the users participate in the opportunistic dissemination. This means that operators could offload their network efficiently without needing to deploy additional caching infrastructure.

    Information services based on user profile communication1999Conference paper (Refereed)
    Abstract [en]

    Web-based, user-adaptive information services impose a difficult requirement on user modeling: the inference schema for user modeling and user-adapted information retrieval must be maintained over time. There are two reasons for this: 1) the information itself may change; and 2) the user group is largely unknown from the start, and may change during the usage of the system. To address these problems, we view profile structures and information classifications as means of communication as well as means for automatic information retrieval. Users communicate their information needs, and editors communicate the structure and content of available information. Our focus is to provide tools in which such communication can be efficiently accomplished. These tools are then used to enhance the day-to-day information retrieval in terms of information filtering and search. In this paper, we propose a design for web information services based on user profile communication. We illustrate the approach by an example application, in which conference and workshop calls are collected and distributed to interested users. We present the results of an initial study of this system, which points towards the most important characteristics of this collaboration. Finally, we discuss future extensions for the system.

    Can readers understand their profiles: a study of user profiling for information filtering2001Conference paper (Refereed)
    Abstract [en]

    The aim in information filtering is to provide users with a personalised selection of information, based on a description of their interest profile. These can be automatically generated or set by users. We can expect that users sometimes will want to be able to review their profiles even if they are system generated. We present a study of the effects of combining automatic profiling with explicit user involvement. Firstly, we wanted to explore if a machine-learned profile would benefit from being based on an initial explicit user profile. Secondly, we tested if profiles that provided better filtering also were better liked by users. Finally, we tested if users could make improvements to machine-learned profiles. We found that the initial set-up of a personal profile was effective, and yielded performance improvements even after feedback training. However, the study showed no correlation between users ratings of profiles and their filtering performance. Neither were there any conclusive evidence that users could improve on the system-generated profiles.

    ConCall: An information service for researchers based on EdInfo1998Report (Other academic)
    Abstract [en]

    In this paper, we present new types of web information services, where users and information brokers collaborate in creating a user-adaptive information service. Such services impose a novel task on information brokers: they become responsible for maintaining the inference strategies used in user modeling. In return, information brokers obtain more accurate information about user needs, since the adaptivity ensures that user profiles are kept up to date and consistent with what users actually prefer, not only what they say that they prefer. We illustrate the approach by an example application, in which conference calls are collected and distributed to interested readers.

    ConCall: Edited and Adaptive Information Filtering1999Conference paper (Refereed)
    Abstract [en]

    The information overflow problem is not simply one of information retrieval and information filtering: the user (reader) might also require aid in summarizing the retrieved information and judging its accuracy and quality. This shows that there is a clear role for the information broker, the human expert that gathers, structures, and evaluates information. Typically information-brokering services of today utilize a predefined classification schema for information. Readers can individualize the service by selecting from the predefined categories. This approach has many disadvantages. First, the individual readers must select between classes of information that may be orthogonal to their real interests. Second, they are forced to use the broker's classification not only for retrieval, but also for structuring the retrieved information. Third, it becomes impossible for readers to indicate that they are looking for types of information that are not covered by the service. Finally, as the information changes over time, the classification schema may have to change. In the EdInfo project [1] we have chosen a different approach. Editors, information brokers, readers, and information services may all use different classification schemas, and change them over time. Techniques from collaborative and intelligent filtering as well as information retrieval are used to create tools that allow services, brokers, and readers to communicate and synchronize their classification schemas.

    Digital Libraries: Information Broker Roles in Collaborative Filtering1998Conference paper (Refereed)
    Abstract [en]

    The main goal of the EdInfo project [1] is to utilize human information brokers, or editors, as a resource in adaptive information systems. An information broker can be any of the following: The dedicated expert that collects and potentially reviews literature within a restricted area of interest; The journalist that produces articles with specific reader groups in mind; The librarian that organizes incoming information and directs readers to various sources; The professional information broker, that processes specific information requests, seeks for appropriate information sources, and produces summaries of the obtained information. The common characteristic of these roles is that the information broker has some kind of understanding of what his or her customers want, and is willing to adapt to these needs. Information brokers collect information from various sources, evaluate its relative importance and then choose whether to include the information as it is, disregard it, summarize it, or perhaps rewrite or illustrate it differently than in the original source.

    Deriving Cellular Network Structure From Inferred Handovers in a Cellular Association Trace2015In: Proceedings of the 6th International Workshop on Hot Topics in Planet-Scale Measurement (HotPlanet '15), 2015, 16Conference paper (Refereed)
    Abstract [en]

    A cellular association trace consists of timestamped events recording user activity in labeled cells in a cellular network. From such data one can infer that if a user appears in two different cells within a short span of time, that a handover took place, and that the coverage areas of the two cells overlap. That is, one can infer geographic information from handover behavior. One would like to expand this kind of inference to a larger scale, perhaps reconstructing a proximity graph of the cellular sites, or creating an approximate 2-dimensional embedding of the cells. We have analyzed a large-scale cellular association trace of several months of activity for several million users on a 3G network, and have found that handover behavior is actually incredibly diverse and complicated, making it very dicult to make any sort of global inferences, even in small sections of a network. In this paper we present some stable elements of handover behavior, and present several methods one can use to extract proximity information from such a trace.

    Intelligent data-intensive IoT: A survey2016In: 2016 2nd IEEE International Conference on Computer and Communications (ICCC), 2016, p. 2362-2368, article id 7925122Conference paper (Refereed)
    Abstract [en]

    The IoT paradigm proposes to connect entities intelligently with massive heterogeneous nature, which forms an ocean of devices and data whose complexity and volume are incremental with time. Different from the general big data or IoT, the data-intensive feature of IoT introduces several specific challenges, such as circumstance dynamicity and uncertainties. Hence, intelligence techniques are needed in solving the problems brought by the data intensity. Until recent, there are many different views to handle IoT data and different intelligence enablers for IoT, with different contributions and different targets. However, there are still some issues have not been considered. This paper will provide a fresh survey study on the data-intensive IoT issue. Besides that, we conclude some shadow issues that have not been emphasized, which are interesting for the future. We propose also an extended big data model for intelligent data-intensive IoT to tackle the challenges.

    Understanding Online Shopping and Offline Mobility Behavior in Urban Area from the View of Multilayer Network2016In: 2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC), 2016, 8, p. 416-421, article id 7974608Conference paper (Refereed)
    Abstract [en]

    The interactive nature of the Internet offers many opportunities to increase the efficiency of online shopping by improving availability of product information, enabling direct multi-attribute comparisons, and reducing buyer search costs. A great body of research focuses on how consumers shop online or why and how online shopping impacts urban development, but the understanding of mutual influence between online and offline behavior of consumers remains somewhat underserved. This paper bridges that gap by quantifying the relationship between consumers' online shopping and offline mobility behavior. The results of the study give insights to further understand human behavior from both a cyber and real world point of view, which may help to place location based targeted advertisements, and plan commercial & retail centers in urban areas.

    Requirements and Challenges for IoT over ICN2015Other (Other academic)
    Abstract [en]

    The Internet of Things (IoT) promises to connect billions of objects to the Internet. After deploying many stand-alone IoT systems in different domains, the current trend is to develop a common, "thin waist" of protocols forming a horizontal unified, defragmented IoT platform. Such a platform will make objects accessible to applications across organizations and domains. Towards this goal, quite a few proposals have been made to build a unified host-centric IoT platform as an overlay on top of today's host-centric Internet. However, there is a fundamental mismatch between the host-centric nature of todays Internet and the information-centric nature of the IoT system. To address this mismatch, we propose to build a common set of protocols and services, which form an IoT platform, based on the Information Centric Network (ICN) architecture, which we call ICN-IoT. ICN-IoT leverages the salient features of ICN, and thus provides seamless mobility support, scalability, and efficient content and service delivery. This draft describes representative IoT requirements and ICN challenges to realize a unified ICN-IoT framework. Towards this, we first identify a list of important requirements which a unified IoT architecture should have to support tens of billions of objects, then we discuss how the current IP-IoT overlay fails to meet these requirements, followed by discussion on suitability of ICN for IoT. Though we see most of the IoT requirements can be met by ICN, we discuss specific challenges ICN has to address to satisfy them. Then we provide discussion of popular IoT scenarios including the "smart" home, campus, grid, transportation infrastructure, healthcare, Education, and Entertainment for completeness, as specific scenarios requires appropriate design choices and architectural considerations towards developing an ICN-IoT solution.

    Prediction of user app usage behavior from geo-spatial data2016In: Proceedings of the Third International ACM SIGMOD Workshop on Managing and Mining Enriched Geo-Spatial Data, 2016, 7, article id 7Conference paper (Refereed)
    Abstract [en]

    In the era of mobile Internet, a vast amount of geo-spatial data allows us to gain further insights into human activities, which is critical for Internet Services Providers (ISP) to provide better personalized services. With the pervasiveness of mobile Internet, much evidence show that human mobility has heavy impact on app usage behavior. In this paper, we propose a method based on machine learning to predict users' app usage behavior using several features of human mobility extracted from geo-spatial data in mobile Internet traces. The core idea of our method is selecting a set of mobility attributes (e.g. location, travel pattern, and mobility indicators) that have large impact on app usage behavior and inputting them into a classification model. We evaluate our method using real-world network traffic collected by our self-developed high-speed Traffic Monitoring System (TMS). Our prediction method achieves 90.3% accuracy in our experiment, which verifies the strong correlation between human mobility and app usage behavior. Our experimental results uncover a big potential of geo-spatial data extracted from mobile Internet.
