Abstract :
It is well known that opportunistic relaying combats wireless fading and network coding in multicast reduces retransmission times. In this article, a network coded multicast retransmission scheme based on opportunistic relaying (NCMR-OR) is proposed, which combines the two above techniques to further improve the efficiency of wireless multi-hop multicast. The outage probability and transmission bandwidth are deduced when two destinations are involved. The numerical results show that NCMR-OR is more efficient than the schemes that employs either opportunistic relaying or network coding in multicast.
