【摘要】 在Ad hoc网络中,现有的QoS路由都是基于目的地址的选路,当源节点针对同一个目的节点需要先后建立两个或者多个实时业务流的时候,多个流所采用的是同一条路径,而这个路径上的的资源是为第一个数据流预留的,不能够同时满足所有流的QoS资源要求,从而导致几个数据流争用资源,使得几个流都无法保证QoS要求。针对这个问题,本文提出了基于流的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。
【Abstract】 Available QoS routing protocols in ad hoc networks are based on destination address. But under these protocols, when a sources node want to establish several data flows to the same destination node, these flows go through the same path. But the resource that reserved in the path is just for the first data flow, this make the route cannot meet the QoS require of these flows. This paper presents a QoS routing protocol based on data flow to resolve mis problem. Simulation result show that the protocol can meet the QoS require of the data flows.
