摘　　要：通过对Ad hoc路由协议AODV及其相关改进协议的研究,提出了一种基于相关节点的多路径负载均衡QoS单播路由协议kn-AODV.该协议利用Ad hoc网络的路由相关性,并结合TDMA带宽计算方法选取关节点,在关节点上实现网络流量的汇聚与分流.实验表明,该协议满足了一定的QoS要求,在一定程度上实现了网络流量负载均衡.与原协议AODV相比,分组成功抵达率最大可提高14%,路由负载比最大可减小13%.By researching the Ad hoc network routing protocol AODV and other related improvement,this paper presents a load-balancing multi-path unicast QoS routing protocol,called kn-AODV.The protocol uses the routing relevance to the Ad hoc,combining with the methods calculating the bandwidth,TDMA to select the key-nodes,which is used to achieve the traffic＇s convergence and shunt.Experiments show that the protocol meets certain QoS requirements,and achieves the traffic load balancing to a certain extent.Compared with the AODV,the highest successful ratio of packet passed increased 14%,and the highest routing load decreased 13%.
