First we do a deep analysis on dynamic source routing (DSR) in the ad hoc network. We introduce the process of the routing and the format of the packet head. Also we find some problems about supporting QoS in DSR.

• 接下来是本文的重点,首先本文对无线Ad Hoc网络中的动态源路由协议(DSR)进行了深入的研究,包括协议过程和报头格式,并且分析了DSR协议在支持QoS方面所存在的问题;
