Interference in wireless networks is one of the key-capacity limiting factor.The multicast capacity of an ad- hoc wireless network decreases with anincreasing number of transmitting and/or receiving nodes within a fixed area.Digital Network Coding (DNC) has been shown to improve the multicast capacityof non-interfering wireless network. However recently proposed Physical-layerNetwork Coding (PNC) and Analog Network Coding (ANC) has shown that it ispossible to decode an unknown packet from the collision of two packet, when oneof the colliding packet is known a priori. Taking advantage of such collisiondecoding scheme, in this paper we propose a Joint Network Coding basedCooperative Retransmission (JNC- CR) scheme, where we show that ANC along withDNC can offer a much higher retransmission gain than that attainable througheither ANC, DNC or Automatic Repeat reQuest (ARQ) based retransmission. Thisscheme can be applied for two wireless multicast groups interfering with eachother. Because of the broadcast nature of the wireless transmission, receiversof different multicast group can opportunistically listen and cache packetsfrom the interfering transmitter. These cached packets, along with the packetsthe receiver receives from its transmitter can then be used for decoding theJNC packet. We validate the higher retransmission gain performance of JNC withan optimal DNC scheme, using simulation.
