AODV路由协议性能的优化仿真

AODV performance optimization simulation

针对标准AODV路由协议中,目标节点选择一条端到端跳数最小的路径作为源节点到目标节点的路径,而采用最小跳路由的路由协议所选的路径在某些情况下并非最优路径的问题。提出选择一条数据传输速率高的路径,作为源节点到目标节点的路径,称为HDR_AODV协议。设计了HDR_AODV协议的RREQ和RREP分组格式,在OPNET上实现了HDR_AODV的功能,并且通过实验。结果表明,从延时、吞吐量、丢包数量等网络性能评测参数HDR_AODV的性能要优于标准AODV。

For standard AODV routing protocol choose the smallest end-to-end path for a target node hops as the source node of the path to the destination,but the use of minimum-hop routing path routing protocol selected is not,in some cases,the optimal path.In this paper,based on the standard AODV,choice of a maximum data transfer rate of the path as the choice of routing parameter,referred to as HDR_AODV.Designed the RREQ and RREP message format of HDR_AODV,achieved the function of HDR_AODV in the OPNET simulation platform,and through experiments,from the delay,throughput,data dropped such as network performance verified HDR_AODV better than standard AODV.
