Research on an Improved Algorithm for Wireless Network Maximum Throughput Based on COPE Protocol

Network coding has reached a goal of significant throughput improvement. Previous work has analyzed the two main features of the COPE protocol: "opportunistic listening" and "opportunistic coding", but in some scenarios, it does not work well on Encoding. In order to further enhance the throughput of COPE protocol for wireless transmission, this paper proposes a new approach based on "opportunistic asynchronous transmission coding CACM". A comparative simulation experiments on four different transport protocol is performed and the result shows that the throughput of COPE, CACM-nP and CACM protocols has been significantly improved by 122%, 133% and 139% respectively over the Unicast protocol. This work provides a guidance for further designing routing / MAC on network coding.
