Physical layer (PHY) network coding (PLNC), which performs the operation of network coding at physical layer, is an attractive
means to improve throughput of wireless multi-hop networks. The PLNC requires multiple sending nodes to transmit
their packets with accurate synchronization at symbol-level. Therefore, in many works of literature, the centralized scheduling with perfect
synchronization has been assumed to be employed on top of PLNC. Furthermore, perfect CSI has also been assumed when
end-nodes attempt to decode their desired packets. However, these assumptions are challenged when we attempt to apply PLNC to
large-scale and distributed networks. Therefore, in this paper, we propose a distributed MAC protocol for wireless multi-hop network
employing PLNC. The proposed MAC protocol is a random access protocol, which solves the PHY-specific problems, such as
synchronization and CSI, jointly with distributed scheduling at MAC layer.
We evaluate throughput of PLNC employing the proposed MAC protocol by computer simulation, and
compare it with that of conventional relaying. With the numerical results, we investigate
the effectiveness of PLNC in distributed wireless multi-hop networks. |
