摘　　要：已有ad hoc网络中的QoS路由都是基于目的地址的选路并预留资源,当源节点针对同一个目的节点先后建立两个或者多个实时业务流的时候,将导致几个数据流争用资源,使得几个流的QoS都无法得到保证。针对这个问题,文章提出了基于流的QoS路由机制,并且进行了仿真分析,仿真结果表明这种机制能够解决这个问题,使QoS得到保证。Most of existing QoS routing protocols for ad hoc networks were based on destination address to route packets and reserve resources. When a sources node establishes successively several data flows to the same destination node, these flows would contend for the resource pre-reserved by the nodes, as results none of QoS of these flows would be satisfied. This paper presented a QoS routing protocol based on data flow to resolve this problem. Simulation results show that the protocol can meet the QoS requirements of the data flows.
