抗毁的混合移动自组织网路由策略

摘要

Concerning that the performance of Mobile Ad Hoc NETwork (MANET) with normal route method degrades obviously when being under attack in battlefield, a new STHR route strategy which integrating AODV( MANET route method) and Spay & Waiter protocols( DTN route method) to achieve high survivability was proposed in this paper. And to reduce the total network load, the method for choosing DTN nodes was designed. At the situation of hard network attacking, the target node may not be searched by AODV search extending ring. Then the zone covering nodes called ZCSEN in this paper would be used to start DTN route progress. In this way, the performance of MANET becomes stable even when it is under attack. The experimental results by ONE'show that the delivery rate of STHR is better than AODV and the delay time is shorter than Spay & Waiter route protocol.%针对战场毁伤条件下移动自组网(MANET)普通路由算法性能下降的问题,在舍有抗毁增强节点的混合MANET网络中,融合了普通MANET路由和容迟网络(DTN)路由设计了抗毁性增强路由协议STHR,并且为了降低网络负载和冲突对STHR中抗毁增强节点的选取算法进行了设计.在网络遭受毁伤甚至出现分割情况下,MANET路由扩展环无法到达目标节点,但借助具有区域覆盖特性的抗毁增强节点转入DTN路由,可以保证在一定时延容忍前提下,仍能保持较高的分组投递率.通过ONE仿真平台实验,结果表明在毁伤情况下,STHR的分组投递率要优于AODV路由,而路由时延低于DTN喷雾等待路由.
