In order to adapt to the wireless network broadcast transmission rate limit, and effectively solve network throughput performance optimization problem in wireless network. This paper researched and analysed network coding method adapt to the wireless network broadcast transmission rate. Firstly, optimize network throughput performance as the first element, designed a global algorithm (GA_NCS) of wireless network channel scheduling strategy, and supported coding perception. Secondly, proofed GA_NCS problem was NP-hard and PTAS solutions was not exist. Finally, this paper designed a new heuristic algorithm for network coding (I-TPO). Experiments showed, I-TPO not only effectively improved newwork throughput, but also had a lower time and computational complexity.
