Charter 6 talks about the some rate control mechanisms of real-time multimedia stream in wireless networks. Firstly, we study an analytical rate control scheme& ARC which is based on wireless TCP throughput model generalized in this charter. 在第六章,我们研究了无线网络实时多媒体业务传输协议的核心&无线速率控制机制,首先研究了一种基于模型的分析速率控制机制ARC,并推导出无线链路中的TCP吞吐率模型。
