Throughput optimization in multi-radio multi-channel wireless networks using network coding

One major problem of wireless mesh networks is low throughput and on the other hand, network coding (NC) is a reliable solution to alleviate this problem. In this paper, we evaluate the throughput gain of various intersession wireless NC schemes, including signal level (analog) NC and packet level NC, which may include non-duplex flows, over the traditional non-NC schemes in multi-radio, multi-channel and multi-hop networks. We also propose a routing approach in order to increase NC opportunities and evaluate its performance in wireless ad-hoc networks in terms of network throughput
