Abstract
In order to enhance throughput in wireless sensor networks (WSNs), we propose a transmission rate optimized cooperative MAC (TRO-CMAC) protocol. The protocol always adopts the cooperative transmission with high transmission rates to replace the direct transmission with low transmission rate. A sender preselects two best candidate relays from its relay information table according to recent equivalent transmission rate and channel condition for use in cooperative transmission. These two relays contend to become the final best relay with instantaneous cooperative transmission rate and channel condition. Simulation results show that TRO-CMAC protocol can obtain higher throughput than those of the RCF-CMAC and 2rcMAC protocols.
