An Energy Saving Scheme Based on Network Coding in WSN

Abstract

Energy efficient communication is a key issue in energy constrained wireless sensor network (WSN). Network coding can reduce transmission times and thus help to save transmission and reception energy in many wireless networks. In this paper, we propose a new scheme which applies network coding to WSN. And we compare the energy performance of our scheme, conventional scheme and cooperative diversity scheme. Results show that network coding scheme has better energy efficiency than other schemes especially when the transmission power is low.
