A multirate cooperative MAC protocol employing statistic channel state information

A multirate cooperative MAC (MC-MAC) protocol is designed for networks with slowly-changing channels between nodes. In this protocol, the statistic channel state information is used to estimate the transmission rate and to select the relay nodes, and the work is done on the source side to avoid collision in the distributed relay nodes selection procedure. The final numerical simulation shows that the throughput performance of the MC-MAC protocol is better than that of similar protocols under the given scenario.
