Abstract
Network coding (NC) enables us to mix two or more packets into a single coded packet at relay nodes and improve performances in mobile ad hoc networks (MANETs). Sliding window network coding is a variation of NC that is an addition to data packet streaming and improves the data delay on MANETs. In this paper, we propose a Sliding Window Network Coding in MANETs (SWNCM). SWNCM preserves the degree distribution of the encoded data packets through the recombination at the nodes. SWNCM enables to control the decoding complexity of each sliding window independently from the data packets received and recover the original data. The performance of the SWNCM is studied using NS2 and evaluated in terms of the network throughput, encoding overhead, decoding delay, packet transmission rate when data packet is transmitted. The simulations result shows that the SWNCM with our proposition can significantly improve the network throughput and achieves higher diversity order.
