  4. 3. Coping with Misbehavior in Mobile Ad-hoc Networks

    Författare :Sonja Buchegger; Jean-Yves Le Boudec; EPFL; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mobile ad-hoc networks; incentives; cooperation; reputation systems; Bayes; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : n this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward correctly? Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. LÄS MER

  5. 4. Cooperative Context-Aware Setup and Performance of Surveillance Missions Using Static and Mobile Wireless Sensor Networks

    Författare :Edison Pignaton de Freitas; Tony Larsson; Carlos Eduardo Pereira; Franz Josef Rammig; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surveillance systems; Wireless sensor network; Cooperative sensors; Mobile sensors; Biologically-inspired networking; Context awareness;

    Sammanfattning : Surveillance systems are usually employed to monitor wide areas in which their usersaim to detect and/or observe events or phenomena of their interest. The use ofwireless sensor networks in such systems is of particular interest as these networks can provide a relative low cost and robust solution to cover large areas. LÄS MER

  7. 5. Cooperative Privacy and Security for Mobile Systems

    Författare :Hongyu Jin; Panagiotis Papadimitratos; Tuomas Aura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The growing popularity of powerful mobile devices, along with increased computation and storage of computing infrastructure, opened possibilities for versatile mobile system applications. Users, leveraging sensing capabilities of the devices, can collect rich data and exchange the data with diverse Service Providers (SPs) or their close neighboring devices. LÄS MER
