摘要: Supporting video applications over 802.11 wireless local area networks is a challenging task due to the constant fluctuations in channel error rates and inefficiency of MAC layer. New compression technologies, such as H.264, provide network adaptation layer for adapting output encoder characteristics underlying transport network. In this article we demonstrate that it possible improve performance H.264 WLANs through cross-layer design optimizes encoded packet sizes. We propose use aggregation fragmentation mechanisms create optimal frame lengths. also investigate several application
