Wireless Peer-to-Peer Mutual Broadcast Via Sparse Recovery

Consider a problem frequently seen in wireless peer-to-peer networks: every node has messages to broadcast to its peers, namely, all nodes within one hop. Conventional schemes allow only one transmission to succeed at a time in a two-hop neighborhood, because simultaneous transmissions in the neighborhood collide, and affordable radio is half-duplex and cannot simultaneously transmit and receive useful signals. In this paper, the authors propose a novel solution for the peer-to-peer mutual broadcast problem, which exploits the multi-access nature of the wireless medium and addresses the half-duplex constraint at the fundamental level.
