Using network coding in wireless networks can increase throughput and reduce energy consumption. Recently there are many works focusing on how to utilize network coding to increase throughput while there are few works considering the quality of service. This paper focuses on network coding based broadcast scheduling in wireless networks with the packet delay constraint and aims at minimizing the number of retransmissions. We will combine two encoding and scheduling schemes, analyze their respective advantages and disadvantages, and dynamically select the scheme. Simulation results show that our algorithm can reduce the number of retransmissions.
