  1. 1. Secure and Privacy-Aware Data Collection in Wireless Sensor Networks

    Författare :Ioana Rodhe; Christian Rohner; Per Gunningberg; Roberto Di Pietro; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secure Data Collection; Key Distribution; Location Privacy; Quality of Information; Wireless Sensor Networks; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : A wireless sensor network is a collection of numerous sensors distributed on an area of interest to collect and process data from the environment. One particular threat in wireless sensor networks is node compromise attacks, that is, attacks where the adversary gets physical access to a node and to the programs and keying material stored on it.

  3. 2. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications

    Författare :George Yuejin Liu; Gerald Maguire; Randy Katz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile Computing; Mobile-API; Mobile Agent; Mobile Floating Agent; Intelligent Agent; Full-Mobility; Mobility Architecture; Mobility Awareness; Location Awareness; Location Prediction; Mobile Personal Communications.;

    Sammanfattning : The emergence of wireless mobile computing, especially the mobility of computers, introduces challenging new problems that were encountered in neither the design and implementation of conventional mobile networks or in fixed computer networks. A critical and challenging problem, for mobile computing and personal communications, is how to fully cope with the special characteristics of the mobile wireless environment, i. LÄS MER

  7. 5. Performance Analysis of Opportunistic Content Distribution via Data-Driven Mobility Modeling

    Författare :Ljubica Pajevic; Viktória Fodor; Thrasyvoulos Spyropoulos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic communication; mobility; content distribution; network performance modeling; trace-collection analysis; stochastic models.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : An opportunistic network is formed by co-located mobile users in order to exchange data via direct wireless links when their devices are within transmission range, without relying on the use of fixed network infrastructure. In this thesis we investigate the capabilities of opportunistic networks and cover two main areas: data-driven modeling of user mobility and analytic performance evaluation of location-aware opportunistic content distribution.
