摘　　要：提出一种6LoWPAN嵌套移动网络路由优化方案,在此方案中,6LoWPAN移动网络节点无须经过家乡代理也无须建立隧道即可与通信节点通信,节省了数据传输开销,缩短了数据传输延迟。提出了移动路由器转交地址的分层结构,根据此分层结构,提出了基于最短路径的移动路由器转交地址配置算法,缩短了数据传输延迟。从理论和仿真两个角度对所提出的路由优化方案的路由优化开销、路由延迟及路由代价等性能参数进行了比较分析,分析结果验证了本方案的有效性和高效性。This paper proposed a scheme for routing optimization of 6LoWPAN nested mobile networks.In the scheme,a 6LoWPAN mobile network node could communicate with a correspondent node without passing the home agent of the correspon-ding mobile router or establishing a tunnel,which reduced the cost for data transmission and shortens the delay time of data transmission.The scheme created the layered structure for a mobile router＇s care-of address,and proposed the care-of address configuration algorithm based on the shortest path.From the perspectives of theory and simulation,analyzed the proposed scheme＇s performance parameters,including routing optimization cost,routing cost and routing delay,and the analytical results show the effectivity and efficiency of the scheme.
