Physical layer network coding (PNC) is a relatively new technique that performs network coding at the physical layer, by viewing overlapping data transmissions as their linear combinations. While existing research on PNC usually focuses on simple network topologies (e.g., the two way relay channel), it appears promising to further explore the opportunities of applying PNC in a large, general, multi-hop wireless network. This talk covers two projects along this direction. In the first project, we show how PNC can be combined with signal alignment (SA), another technique inspired from interference alignment (IA), for application in MIMO wireless networks. In the second project, we advocate Buddy Routing, a pair-to-pair wireless routing paradigm enabled by PNC, in favor of the traditional node-to-node routing schemes, in a large scale wireless sensor network or NANO network.
