本文仿真研究Ad-hoc無線網(wǎng)絡(luò)環(huán)境下MPEG-4流媒體的通信性能，在分析和探討無線實時流媒體網(wǎng)絡(luò)性能瓶頸以及各類圖像幀的影響權(quán)值的基礎(chǔ)上，提出一種性能改進方案---有選擇地丟棄影響權(quán)值較小的B圖像幀，這一方案用以緩解無線流媒體通信的性能瓶頸，改善流媒體的通信性能。

【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
