  2. 1. Medium access control for vehicular ad hoc networks

    Author : Katrin Sjöberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle-to-vehicle communications; SOTDMA; self-organizing TDMA; cooperative system; C-ITS; V2V; ETSI ITS-G5; traffic safety; ISO CALM M5; STDMA; VANET; IEEE 802.11p; V2X; MAC; CSMA; cooperative ITS; medium access control; WAVE; DSRC; vehicular ad hoc networks; scalability; real-time communications;

    Abstract : Cooperative intelligent transport systems (C-ITS), where vehicles cooperate by exchanging messages wirelessly to avoid, for example, hazardous road traffic situations, receive a great deal of attention throughout the world currently. Many C-ITS applications will utilize the wireless communication technology IEEE 802. READ MORE

  5. 3. 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

  6. 4. On Medium Access for Wireless Ad-hoc and Sensor Networks

    Author : Arash Tahmasebi Toyserkani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MAC; Transmission range; Interference range; Taffic Safety; Sensor Networks; TDMA; CSMA;

    Abstract : The medium access control (MAC) is a sub-layer of the data link layer, thesecond layer of the open system interconnection (OSI) model. The MAC sub-layeris responsible for organizing the access to the shared channel and it is due tothis important responsibility that the performance of networks is substantiallyinfluenced by the MAC protocol.

  7. 5. 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
