In this paper we present an energy consumption model for a network coding-based cooperative ARQ (Automatic Repeat reQuest) scheme for wireless networks. Applying network coding techniques, we achieve a significant enhancement in the energy efficiency of the network without compromising the Quality of Service in terms of throughput and packet delay. In order to evaluate the proposed solution, we compare our protocol with simple cooperative ARQ protocols, where the retransmissions take place via relays without any network coding capabilities. Finally, both analytical and simulation results are used in order to verify our conclusions.
