摘要：

This paper introduces and analyzes relaying techniques that increase the achievable throughput in multi-hop wireless networks by applying network coding over bi-directional traffic flows. We term each such technique as Bi-directional Amplification of Throughput (BAT)-relaying. While network coding is normally performed by combining decoded packets, here we introduce a relaying method based on Amplify-and-Forward (AF), where the relay node utilizes the inherent combining of packets provided by simultaneous transmissions over a multiple access channel. Under low noise levels, AF BAT-relaying offers a superior throughput performance. The unconventionality of AF BAT relaying opens many possibilities for further research.
