| 摘 要： | 基于QoS路由及保障路由实施是支持MANET应用的关键.为解决MANET中QoS问题,在移动预测机制下提出了一种基于QoS保障的组播协议.该协议通过簇头选举,移动预测和QoS控制策略在组播源与含目的节点的组播簇头间确定最稳传输路径,并采用基于动态资源管理的QoS路由模型来保障路由实施.仿真结果显示该方案可获得较高传输成功率和较低控制开销,能有效支持MANET中具有QoS需求的组播传输.

| Abstract: | Both of QoS routing and guarantee transmission of QoS routing are some important factors for MANET.In order to resolve QoS problem,a multicast protocol based on QoS guarantees under mobility prediction is proposed in MANET.Through using some policies,such as electing of cluster head,mobility prediction and QoS control,some steadiest paths are picked up in the nodes of network both clusterheadof including sourcenodeand cluster heads of including destination nodes.At the sametime,routing transmission is guaranteed by QoS routing model based on dynamic resource management.Simulation results show that the scheme has good network performance with low control overload and high packet delivery ratio,and efficiently supports transmitting multimedia with QoS requi-rements in MANET. |
