本文仿真研究Ad-hoc无线网络环境下MPEG-4流媒体的通信性能，在分析和探讨无线实时流媒体网络性能瓶颈以及各类图像帧的影响权值的基础上，提出一种性能改进方案---有选择地丢弃影响权值较小的B图像帧，这一方案用以缓解无线流媒体通信的性能瓶颈，改善流媒体的通信性能。

【Abstract】This paper presents a simulation study of media streaming performance in Ad-hoc environment，after analyzing and investigating the performance bottleneck of wireless media streaming and the weight of all kinds of image frames, an strategy that selectively discard the less affected B- images frame is proposed, which alleviates performance bottleneck and improves the performance of media streaming communication in WLANs significantly.
【Key words】media streaming；image frame；performance bottleneck ；NS
