| 摘 要： | 针对移动自组网(Ad hoc)的特点和AODV协议的可扩展性,提出了一种适合Ad hoc的选播QoS路由协议AQAODV,该协议在考虑选播路由特点的基础上,扩展AODV以支持QoS需求,并采用局部路由恢复技术,在动态变化的Ad hoc网中实现了一种高效的选播QoS路由.仿真结果表明,AQAODV协议在带宽、时延和平均路由开销等方面较AODV协议具有明显的性能优势.

| Abstract: | According to the features of Ad hoc networks and expandable character of AODV,a new anycast QoS routing protocol(AQAODV) based on AODV that is suitable for Ad hoc networks is proposed.On the basis of considering features of anycast routing,AODV is expanded to support requirement of QoS and the local route recovery mechanism is combined.It accomplished an effective anycast QoS routing protocol in dynamic Ad hoc networks.The simulation results show distinct advantages of AQAODV to AODV on the performance of bandwidth efficiency ratio,packet delay and average overhead load. |
