摘　　要：QoSAODV协议是目前自组网QoS路由协议的研究热点.由于只能由目的节点返回路由确认RREP,它的协议开销较大.提出了一种基于QoS AODV的改进协议AQ-AODV(Advanced Q-AODV).通过建立QoS分级路由表并改进QOS-LOST分组的转发机制,可由中间节点返回RREP.仿真实验表明,AQ-AODV的协议开销比AODV和QoS AODV有较大幅度降低,同时分组递交率和分组平均传输延迟也略有改善.Research on routing protocol QoS AODV for mobile ad hoc network is hot. Since it only allows destination node to return routing reply packet RREP, the routing overload is quite high. AQ-AODV（Advanced QoS AODV） is proposed to allow intermediate node to return RREP by constructing routing table with different QoS levels and renewing the propagating mechanism of QOS-LOST packet. Simulation experiment shows that AQ-AODV has quite lower overload than AODV and QoS AODV, also, both the packet delivery ratio and average packet propagating delay are better.
