Wireless Multicast Opportunistic Routing with Dual Network Coding
Wireless Multicast is one of the important problems with applications to opportunistic networks, such as delay-tolerant networks (DTNs), personal, pocket-switched networks (PSNs) etc. Network Coding has received many attentions because it improves potential network throughput and robustness by the way of combining multiple packets in the routers and reducing the transmissions. This paper combines network coding with opportunistic routing to improve the throughput of wireless multicast, where an Inter-coding and Intra-coding scheme is introduced to the traditional multicast routing algorithm (OR-DNC, Opportunistic Routing with Dual Network Coding). Compared with traditional multicast routing without coding and MORE-M, OR-DNC performs better in terms of throughput, transmission reduction and coding gain.
