Abstract
Network coding (NC) enables us to mix two or more packets into a single coded packet at relay nodes and improve performances in wireless networks. Intra-session sliding window network coding is used at the source nodes and inter-session network coding is employed at the relay node to combine the recovered source packets of source nodes. In this paper, we investigate the performance of the network-coded system in terms of the probability that the destination node will successfully recover the source packets of the source nodes. We propose a sliding window network coding in relay wireless networks (SWNC-RN). The performance of the SWNC-RN is studied using NS2 and evaluated in terms of the network throughput, decoding delay, packet transmission rate when data packet is transmitted. The simulations result shows that the SWNC-RN with our proposition can significantly improve the network throughput and achieves higher diversity order.
