Energy Efficient Distributed Receiver Based Cooperative MAC for wireless sensor networks

This article presents a new Energy Efficient Distributed Receiver Based Cooperative Medium Access Control protocol for wireless sensor networks (E²DRCMAC for WSNs). WSNs employ cooperative diversity techniques in order to improve network lifetime and overall network reliability. The proposed MAC scheme focuses on cooperation with overhearing avoidance and reducing transmissions in case of link failures in order to minimize energy consumption in the network to improve the network lifetime. This article also presents an analytical model for the packet delay to show the improved performance when cooperation is introduced as revealed by the simulation results. The findings presented in this article include percentage energy used in the network, throughput, packet delay, and packet delivery ratio.
