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

    University essay from 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. 12. The Evaluation of GeoNetworking Forwarding in Vehicular Ad-Hoc Networks

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Rajapandiyan Rajendran; [2013]
    Keywords : GeoNetworking; Multi-hop Routing; Vehicular Ad-Hoc Networks; Safety Message Dissemination; Geographical Broadcast; Forwarding Algorithm; Timer-based Protocol; Forwarder Selection; Contention-based Forwarding;

    Abstract : In Intelligent Transportation Systems (ITS), disseminating warning messages in a timely and efficient way through wireless short-range communications can save many lives and reduce traffic congestion. A geographical broadcast protocol provides data delivery to specified geographical areas, using multi-hop communications if needed. READ MORE

  4. 13. Real-Time Gait Analysis Algorithm for Patient Activity Detection to Understand and Respond to the Movements

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Inam-ul-Haq ; Adnan Jalil; [2012]
    Keywords : Parkinson s disease; Gait Analysis; Movement Disorder; Wireless Sensors;

    Abstract : Context: Most of the patients suffering from any neurological disorder pose ambulatory disturbance at any stage of disease which may result in falling without showing any warning sign and every patient is different from another. So there is a need to develop a mechanism to detect shaky motion. READ MORE

  5. 14. A vision based on surveillance system using a wireless sensor network

    University essay from KTH/Reglerteknik

    Author : Niklas Lundell; [2010]
    Keywords : ;

    Abstract : The aim of this thesis project is to implement a vision based surveillance system in a wireless sensor network running the Contiki operating system. After a comparative review of experimental cameras the decision fell on the Cmucam3. Hardware and software to integrate the camera with a Tmote Sky mote were created. READ MORE

  6. 15. Algorithm Adaptation and Optimization of a Novel DSP Vector Co-processor

    University essay from Datorteknik

    Author : Andréas Karlsson; [2010]
    Keywords : DSP; SIMD; ePUMA; real-time; embedded; matrix; QR; LU; inverse; determinant; master-multi-SIMD; parallel algorithms; matrix algebra;

    Abstract : The Division of Computer Engineering at Linköping's university is currently researching the possibility to create a highly parallel DSP platform, that can keep up with the computational needs of upcoming standards for various applications, at low cost and low power consumption. The architecture is called ePUMA and it combines a general RISC DSP master processor with eight SIMD co-processors on a single chip. READ MORE
