Abstract
A wireless broadcast retransmission scheme based on the random network coding is put forward for the reliable broadcast in wireless broadcast system. With the strategy to allow the sender to combine and retransmit lost packets by using the random linear codes, the scheme can effectively reduce the number of retransmissions and improve the throughput efficiency. Based on the burst error channel modeled by a two- state Markov chain, analytic solutions are derived for the throughput efficiency of three schemes including the traditional Selective-Repeat ARQ (SR-ARQ), the XOR network coding-based ARQ (XOR-ARQ) and the random network coding-based ARQ (RNC-ARQ).The theoretical and simulation results show that the throughput efficiency of RNC-ARQ is considerably better than the SR-ARQ, while it can achieve the upper bound of throughput performance of the XOR-ARQ under the same channel conditions.
