  1. 26. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

    Författare :Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. LÄS MER

  3. 27. System Design for Opportunistic Networks

    Författare :Sylvia T. Kouyoumdjieva; Gunnar Karlsson; Andrea Passarella; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic communication; system design; mobility; energy-saving mechanisms; device-to-device communication; mobile data offloading; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Device-to-device communication has been suggested as a complement to traditional cellular networks as a means of offloading cellular traffic. In this thesis we explore a solution for device-to-device communication based on opportunistic content distribution in a content-centric network. LÄS MER

  4. 28. Multi-Sensor Data Synchronization using Mobile Phones

    Författare :Jonas Wåhslén; Thomas Lindh; Jens Eliason; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless body sensor networks; wireless personal area network; sport technology; Bluetooth performance; time synchronization; data fusion; mobile phone application.;

    Sammanfattning : Body sensor networking is a rapidly growing technology. Today wearable sensors are used to measure and monitor e.g. pulse, temperature, skin conductance, heart activity, and movement (through GPS or inertial measurement units). LÄS MER

  5. 29. Measurements in opportunistic networks

    Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networks are a subset of delay tolerant networks where the contacts are unscheduled. Such networks can be formed ad hoc by wireless devices, such as mobile phones and laptops. LÄS MER

  7. 30. Authentic Communication and Trustworthy Location in Mobile Networks

    Författare :Felipe Boeira; Mikael Asplund; Marinho Barcellos; Alexey Vinel; Panos Papadimitratos; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Widespread mobile network connectivity has changed society and, consequently, increased our dependency on its proper functioning for transportation, safety, finance, and more. This thesis is concerned with improving the security of mobile networks and focuses on two such instances: vehicular and cellular networks. LÄS MER
