| 摘 要： | 多数Ad hoc网络路由研究聚焦于找到一条连接源和目的节点的路由,而没有考虑网络的QoS需求,一旦数据流量超过了网络所能承受的限度,数据流的传输质量将无从保证。提出了一种AOMDVQ(AOMDV Based on QoS)路由协议,在AOM-DV基础上增加了带宽、时延、跳数和优先级等约束条件,使得在路由发起和路由维护阶段满足一定的QoS需求。仿真结果显示,AOMDVQ协议在高速移动状态下其数据包发送成功率、端到端时延等较AOMDV、MP-AOMDV协议有明显改进。

| Abstract: | Much work on Ad hoc routing recently is focused on finding a path connecting the source node and the destination node,giving less thought to the quality of service.Therefore,there is no quality guarantee for the traffic when the network is overloaded.This thesis presents a kind of routing protocol（AOMDVQ）,which is an improvement on AOMDV.It adds certain restriction condition that consists of bandwidth,delay,hops and priority,which make routing node must meet QoS requirements when the phase of routing initiation and routing maintenance.Simulation result proves that AOMDVQ protocol has an improvement on data delivering rate and end-to-end delay at the status of node move with the high speed. |
