necoMAC: Network coding aware MAC protocol for multirate wireless networks

In this paper we introduce a network coding aware Medium Access Control (necoMAC) scheme that incorporates many protocols such as NCA-2PSP, 2PSP and NCA-CSMA in order to provide data transmission in higher rates with fewer number of transmissions for multirate wireless networks. We create two golden topologies called golden chain and golden triangle, and calculate their energy consumption, overhead ratio, throughput and fairness for each protocol. We also set up a simulation to further analyze the performance of these protocols with the increasing number of nodes and flows. The simulation results show that the proposed scheme provides higher throughput and less energy consumption compared to the conventional CSMA/CA
