  1. 1. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Fredrik Österlind; Uppsala universitet.; Uppsala universitet.; SICS.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation;

    Sammanfattning : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.

  2. 2. Measurements in opportunistic networks

    Detta är en avhandling från Uppsala University

    Författare :Fredrik Bjurefors; Uppsala universitet.; Uppsala universitet.; [2012]
    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

  3. 3. Towards content distribution in opportunistic networks

    Detta är en avhandling från Uppsala University

    Författare :Thabotharan Kathiravelu; Uppsala universitet.; Uppsala universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networking is a new communication paradigm. Content Distribution in opportunistic networks is challenging due to intermittent connectivity, short connection durations and a highly dynamic topology. Research is needed to develop new applications and protocols that can distribute content in opportunistic networks. LÄS MER

    Sammanfattning : Wireless sensor networks are used to collect sensor data in different applications such as environmental monitoring, smart building control, and health care applications. Wireless sensor nodes used are typically small, low-cost, and battery powered. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ioana Rodhe; Uppsala universitet.; Uppsala universitet.; [2012]
    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.
