Abstract
It is known that the network coding-aware routing could promote system performance by exploring network coding opportunities. In this paper, we analyze the benefits brought by the coding-aware routing in terms of energy efficiency. Specifically, we propose a novel Energy Efficient Coding-Aware Scheme (EECAS) that targets to minimize the total energy consumption of all nodes of wireless sensor networks for multiple unicast traffic-flow demands. Furthermore, by formulating a Minimum Time-cost Model (MTM), we propose a TDMA-based energy-efficient scheduling scheme at the MAC layer. Simulation results show that EECAS reduces at most 11% of energy compared to common routing scheme and 6% compared to traditional coding-aware routing scheme.
