This paper considers the problem of maximizing the input rate in a relay assisted network coding (RANC) wireless multicast with packet erasure channels where the relay to destination channels have relatively higher channel gains than the corresponding transmitter to destination channels. Specifically, a new queuing model consisting of several sub-queues at both the transmitter and the relay is introduced. Our objective is to maximize the input rate under the queue stability constraints. First, we formulate it as a linear programming problem to achieve the maximum stable throughput and then applying Lyapunov optimization method a network coding based optimal packet scheduling scheme is obtained. Finally, the simulation results corroborate our method.
