Information Exchange in Wireless Networks with Network Coding and Physical-layer Broadcast

We show that mutual exchange of independent information between two nodes in a wireless network can be efficiently performed by exploiting network coding and the physical-layer broadcast property offered by the wireless medium. The proposed approach improves upon conventional solutions that separate the processing of the two unicast sessions, corresponding to information transfer along one direction and the opposite direction. We propose a simple and practical approach to realize the gain.
