Network Coding Aware Routing Protocol for Lossy Wireless Networks

In this paper, network coding aware routing protocol for lossy wireless networks is proposed. It considers both potential coding opportunity in available route discovery process and link delivery ratio in optimal route selection. In route discovery process, it detects whether current flow can be coded with established flows in networks. And when more than one coding schemes exists in some intermediate node, it can determine coding scheme with the highest priority. Besides, in optimal path selection process, it adopts an improved ETX metric to estimate and choose the path which has lowest transmission count. Simulation results show that our proposed protocol can effectively improve the throughput of lossy wireless networks.
