An enhanced network coding scheme for mobile ad-hoc network

Abstract

Generally, in network coding, relay nodes mix the content of different packets to a single coded packet and broadcast the coded packet on the wireless medium. Network coding is expected to improve throughput and channel efficiency in the wireless multi-hop network. Prior researches have been carried out to employ network coding to wireless ad-hoc network. In this paper, we proposed an enhanced practical network coding scheme for wireless ad-hoc network. In our design, intermediate nodes identify one-hop bidirectional flows for network coding decision. It could make decoding failure probability to zero at neighbor nodes. We expect that the proposed algorithm shall improve decoding success rate of network coded packet. From the simulation, the proposed network coding scheme achieved better performance in terms of coding gain and packet delivery rate than traditional network coding scheme. © 2013 Springer Science+Business Media Dordrecht.
