  1. 1. An IEEE 802.15.4 Packet Error Classification Algorithm : Discriminating Between Multipath Fading and Attenuation and WLAN

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Author : Nan Chen; [2014]
    Keywords : WSN; error discrimination; MFA; WLAN interference; F-BER; RSSI; LQI; CC2420;

    Abstract : In wireless sensor networks, communications are usually destroyed by signal attenuation, multipath fading and different kinds of interferences like WLAN and microwave oven interference. In order to build a stable wireless communication system, reactions like retransmission mechanisms are necessary. READ MORE

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

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem; Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

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

    Abstract : 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. READ MORE

  3. 3. A TinyOS Testbed for CC2420 Transceivers

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Author : Muhammad Asif Jamal; [2013]
    Keywords : TinyOS; Motes; WSN; RSS; testbed; nesC; MICAz; MIB520; Handshaking; Frame length byte;

    Abstract : Wireless Sensor Networks (WSNs) have gained significant consideration these days, as opposed to wired sensor networks, by introducing multi-functional wireless nodes, which are smaller in size. The main advan-tage is that its wireless, so it costs less to install, maintain and reconfig-ure. These sensor nodes are used in various application areas. READ MORE
