摘要: 分析了自组织网络中AOMDV多径路由协议的机制和特点,针对其在拥塞控制和负载均衡的缺点,提出了AOMDV_D协议,在转发RREP消息时根据计算的当前节点负载量适当的延时发送,从而能够自主选择网络中空闲的节点建立主路径。仿真结果表明AOMDV_D协议在网络负载较大的情况下,平均时延和分组投递率都比AOMDV协议更优。Abstract: Based on the analysis of Ad hoc On-demand Multipath Distance Vector routing (AOMDV) protocol and discusses its route discovery process.According to the deficiency of the lacking congestion control and load balance mechanism,this paper proposes AOMDV_D protocol as a result of improving the AOMDV,this protocol can establish an appropriate main path by adding congestion control and load balance.Simulation results show that the AOMDV_D protocol has lower average delay and higher packet delivery ratio comparing with AOMDV protocol in same network environment.
