摘要
多媒体应用的发展使得在Ad Hoc网络中提供服务质量(QoS)保证具有重要的意义。提出了一种基于AODV协议的多约束QoS路由协议(MQAR),扩展了QoS路由表项,允许中间节点发起路由回复(RREP)和资源预留,并且采用局部路由修复机制。仿真实验表明,MQAR协议在保持较高的报文传输率的情况下,有效地减少了路径建立时间和修复时间,大大降低了路由开销。
Providing Quality of Service （ QoS） guarantee for mobile Ad Hoc network is very important due to the rapid growth of multimedia applications. The Multi-bounded QoS-aware Ad Hoc Routing （ MQAR） protocol based on AODV was proposed, which allowed intermediate node to return Route Reply （ RREP） packet and reserve resources by extending QoS routing table, and adopted local route recovery as well. The simulation results show that MQAR protocol can effectively reduce route establishing time, route recovery time and routing overload as well, and the packet delivery ratio remains high.
