Mobile Cooperative WLANs - MAC and Transceiver Design, Prototyping, and Field Measurements
The authors propose a practical Medium Access Control (MAC) protocol and transceiver design for mobile cooperative WLANs. Their MAC protocol integrates Selection Decode-and-Forward (SDF) cooperative relaying into IEEE 802.11. Unlike previous approaches, its cooperative signaling cycle allows communication if the direct link fails even for small signaling frames. Further SDF functions are efficiently supported by the ready-to-use transceiver design. They implement this design, including their MAC protocol, on a Software Defined Radio (SDR) resulting in a cooperative IEEE 802.11g prototype.
