摘    要:移动Ad Hoc网拓扑结构经常变化。自适应后备路由局部修复AODV协议AODV-ABL通过监听RREP包和数据包来产生后备路由,并存于后备路由表中。仅当链路错误时,AODV-ABL才试图利用后备路由表进行局部修复。为提高对网络拓扑变化的自适应性,在AODV-ABL基础上,提出了一种快速自适应后备AODV路由协议AODV-FABL。AODV-FABL合并主路由表和后备路由表,在监听包时同步更新路由,路由能尽快地得到优化。实验结果表明,AODV-FABL取得了比AODV-LR、AODV-ABL更好的包投递率、端对端时延、控制开销和对流量负载变化的适应性。

关 键 词:移动AdHoc网  自组织网络按需距离矢量(AODV)  监听  后备路由

Abstract:The network topology changes frequently in mobile Ad Hoc networks.In AODV-Adaptive Backup with Local repair routing(AODV-ABL)protocol,the backup route can be created by overhearing RREP packets and data packets and can be stored in alternate route table.Only when the link error occurs,AODV-ABL tries to start a local repair process by using alternate route table.In order to improve the adaptability to the network topology changing,a Fast AODV-ABL routing(AODV-FABL)protocol,which based on AODV-ABL,is proposed.AODV-FABL merges the primary route table with the alternate route table,and updates routes when overhearing packets,thus the routes can be optimized as soon as possible.Experimental results show that AODV-FABL has better packet delivery ratio,end-to-end delay,control overhead and adaptability to the variational traffic load than AODV-LR and AODV-ABL.
Keywords:mobile Ad Hoc networks  Ad-hoc On-demand Distance Vecto(rAODV)  overhear  backup route
