A MAC-Layer Network Coding Opportunity Optimization Scheme in Multi-Hop Wireless Networks

In order to improve the performance of multi-hop wireless network, network coding mixes multiple signals in a single channel. A coding scheme proposed previously which is called BEND is a very compelling network coding applications. While it is another way of such programs, but there is still great potential to be developed. This article, based on BEND, expands the width of the potential paths by asking more potential nodes to join so that it increases network throughput and reduces the transmission delay at the same time. It is not a right way neither in theory nor in practical application that increasing the width of the paths unlimitedly by progressive approach. So the best paths width, as well as the network parameters which affecting the paths width is discussed in the final part of this article.
