中文摘要：

在移动自组织网络（MANETs）中常见路由算法的基础上,如单副本路由和泛洪路由,提出了一种基于轨迹相似度的单副本路由算法.针对单副本路由和泛洪路由中存在的问题,如单副本路由中的大传输延迟、泛洪路由中的过量网络资源消耗及由此导致的数据丢失,提出了基于历史轨迹记录相似度的多副本路由算法.通过仿真实验,对所提算法在转发成功率、转发延时及转发次数等性能参数方面进行了评估.实验结果表明,与现有的路由算法相比,所提出的算法具有更好的性能表现,达到了预期的设计目标.

英文摘要：

Based on the analysis of the common routing algorithms in mobile ad hoc networks（ MANETs）,e. g.,single-copy and flooding,a routing algorithm,which uses single copy and the similarities of the trace,is proposed. To address the problems of single-copy and flooding routing,such as the high transmission delay in single-copy routing,the large amount of the network overhead and packet loss in the flooding,we K-copies routing algorithm based on the similarities of nodes trace records. Finally,the algorithms are evaluated in terms of several performance parameters,i. e.,the packet delivery ratio,the average transmission delay and forwarding hops. The results of the simulations show that our algorithms have the better performance than other existing routing algorithms in MANETs.
