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
