  1. 1. Throughput Analysis of Interfering Packet Radio Networks

    Författare :André Stranne; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; energy; collision; packet length; frequency hopping; throughput; successful packet reception probability; heterogeneous packet radio networks; interference analysis;

    Sammanfattning : In this thesis, a probabilistic framework is presented and used for analysis of the throughput of interfering packet-based radio networks, referred to as packet radio networks (PRNs). Previous research on the performance of PRNs covers a wide variety of systems and aspects in varying levels of detail. LÄS MER

  3. 2. Design Space Exploration of Wireless Multihop Networks

    Författare :Urban Bilstrup; Bertil Svensson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multihop networks; wireless sensor networks; Ad hoc networks; Design space; Wireless embedded networks; Packet radio networks;

    Sammanfattning : This thesis explores the feasible design space of wireless multihop networks and identifies fundamental design parameters. In the process of exploring it is important to ignore all details and instead take a holistic view. LÄS MER

  4. 3. 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

  5. 4. Performance Analysis of Cognitive Radio Networks with Interference Constraints

    Författare :Hung Tran; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Spectrum Underlay Access; Interference Constraints; Cognitive Cooperative Radio Networks;

    Sammanfattning : To support the rapidly increasing number of mobile users and mobile multimedia services, and the related demands for bandwidth, wireless communication technology is facing a potentially scarcity of radio spectrum resources. However, spectrum measurement campaigns have shown that the shortage of radio spectrum is due to inefficient usage and inflexible spectrum allocation policies. LÄS MER

  7. 5. Improving TCP Performance in Wireless Multi-hop Networks : Design of Efficient Forwarding and Packet Processing Techniques

    Författare :Jonas Karlsson; Andreas Kassler; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TCP; transport protocols; packet aggregation; multi path routing; wireless mesh networks; Computer Science; Datavetenskap;

    Sammanfattning : Due to the high availability of cheap hardware, wireless multi-hop networks and in particular Wireless Mesh Networks (WMNs) are becoming popular in more and more contexts. For instance, IEEE 802.11 based WMNs have already started to be deployed as means to provide Internet access to rural areas in the developing world. LÄS MER
