  1. 1. Adaptive Coarse-grain Reconfigurable Protocol Processing Architecture

    Författare :Mohammad Badawi; Ahmed Hemani; Zhonghai Lu; Zainalabedin Navabi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Architecture; Reconfigurable Architecture; Protocol Processing; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Digital signal processors and their variants have provided significant benefit to efficient implementation of Physical Layer (PHY) of Open Systems Interconnection (OSI) model’s seven-layer protocol processing stack compared to the general purpose processors. Protocol processors promise to provide a similar advantage for implementing higher layers in the (OSI)'s seven-layer model. LÄS MER

  3. 2. Protocol processing in network terminals

    Författare :Ulf Nordqvist; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The bandwidth and number of users in computer networks are rapidly growing today. The need for added functionality in the network nodes is also increasing. The requirements on the processing devices get harder and harder to meet using traditional hardware architectures. LÄS MER

  4. 3. Energy Efficient Protocols for Active RFID

    Författare :Björn Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

    Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER

  5. 4. Ad hoc routing protocol validation

    Författare :Oskar Wibling; Joachim Parrow; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : We explore and evaluate methods for validation of ad hoc routing protocols which are used to set up forwarding paths in spontaneous networks of mobile devices. The focus is automatic formal verification but we also make an initial account of a protocol performance comparison using structured live testing. LÄS MER

  7. 5. Towards energy efficient protocols for active RFID

    Författare :Björn Nilsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RFID; active RFID; protocol; back-off; carrier sense; energy efficient; wireless networks; active tag; energy consumption; Computer engineering; Datorteknik;

    Sammanfattning : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. LÄS MER
