Completely Opportunistic Approach to Network Coding Using in Wireless Network

Network coding is a new method by which a multicast network can achieve the network capacity determined by the max-flow and min-cut theorem. This paper shows the mutual exchange of independent information between two nodes in a wireless network which can be efficiently combined with network coding and broadcast property offered by wireless medium. It introduces COPE, an opportunistic approach to network coding. Compared with traditional routing, COPE can increase the network and apply for multiple unicast flow efficiently and robustly.
