Variable Length Sliding Window-based Network Coding Algorithm in MANETs

Network coding (NC) consists of intelligently aggregating data packets by means of binary or linear combinations. NC has been considered as one of the possible solutions to the current low throughput, energy consumption, packet loss, non-connectivity and mobility support problems in MANETs. Sliding-window Network Coding is a variation of NC that is an addition to TCP/IP and improves the throughput of TCP on wireless networks. In this paper, we propose a Variable Length Sliding Window-based Network Coding algorithm in MANETs (VLSW-NC). The performance of this VLSW-NC is studied using NS2 and evaluated in terms of the throughput, packet loss probability, and decoding delay when packet is transmitted. The simulations results shows that the VLSW-NC achieved with our proposition can significantly improve the network performance and reliability.
