  4. 2. Energy Efficient Protocols for Active RFID

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

    Abstract : 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. READ MORE

  5. 3. Towards energy efficient protocols for active RFID

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

    Abstract : 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. READ MORE
