Using network coding in wireless sensor networks routing protocol

Energy constraint in wireless sensor networks, have been made the packets routing with essential issues. In event based applications, the inherent constraint of these networks and large packet traffics affects the networks lifetime. Hence, the energy of sensor nodes near the sink node will be exhusted and the duty of WSNs will be affected with this problem. Network coding scheme with encoding and decoding of data packets, have improved the throughput, reduces the average end-to-end delays and resilient the networks against the fails. In this paper, we proposes a routing algorithm using network coding scheme. For selecting appropriate routing paths, the proposed scheme considers the link quality and residual energy of neighbor nodes. Simulation results show that the proposed scheme increases the network reliability and decreases the energy consumption in comparing with other relate scheme.
