In this paper, the authors investigate the benefit of network coding for TCP traffic in a wireless mesh network. COPE, a new architecture for wireless mesh networks is also introduced. Packets are mixed (i.e., coded) by routers from different source nodes to increase the information content during every transmission. Intelligently mixing the packets increase network throughput. The results show that COPE largely increases network throughput. Depending on the traffic pattern, congestion level, and transport protocol used, gains in throughput vary.
