  1. 1. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Författare :Jiahuan Lei; Qingbi Liao; [2014]
    Nyckelord :interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

    Sammanfattning : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. LÄS MER

  3. 2. Compact and Integrated Broadband Antennas : for wireless applications

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Muhammad Afzal Sadiq; [2012]
    Nyckelord :Wireless; Antennas; Integrated; Compact; Dual band;

    Sammanfattning : As the wireless technology maturing, the wireless systems are evolving towards the development of new applications with broad band access and also the higher data rate. This necessity will give rise to the new WLAN standards as well as minimizing the cost, high QoS and security features of the wireless setup. LÄS MER

  4. 3. Industrial WLAN

    Kandidat-uppsats, Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Författare :Pontus Nyman; Stefan Sand; [2011]
    Nyckelord :WLAN; 802.11;

    Sammanfattning : WLAN i form av standarden IEEE 802.11 används inte i större utsträckning i industriell miljö. Vi undersöker hur pass protokollet kan användas för datakommunikation i sådan miljö med avseende på störningskänslighet och datorkraftsbehov, i form av en empirisk undersökning. LÄS MER

  5. 4. Indoor Location Detection using WLAN

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Anqi Luo; Lei Ge; [2010]
    Nyckelord :WLAN; location detection accuracy; arrival signal and processing;

    Sammanfattning : The thesis seeks to improve the accuracy of indoor wireless local area network (WLAN) location detection. The main task of the project is the design and analysis of a solution, which utilizes the packets which are already emitted by WLAN devices. The system consists of a signal receiver and signal processing. LÄS MER

  7. 5. Implementation of a Manycast Protocol in a Partitionable Mobile Ad hoc Network

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för datavetenskap

    Författare :Gustav Nykvist; [2009]
    Nyckelord :mobile ad hoc network; multi-hop; partition tolerance; random-walk gossip-based manycast;

    Sammanfattning : Wireless communication has grown very popular, and communication is the key to success in many situations. However, most of the common technologies today rely on infrastructure and in disaster situations infrastructure might be lost or get severely overloaded. This master thesis concerns intermittently connected mobile ad hoc networks. LÄS MER
