| 摘 要： | IETF在移动IPv6(MIPv6)基础上制定的网络移动性(NEMO)协议规范中,嵌套移动子网的数据传输存在次优路由和多层封装,影响数据包的传输效率.为此,该文在层次移动IPv6(HMIPv6)的基础上,提出了嵌套移动子网的优化方案HRO,引入MAP域优化节点的位置管理,建立优化路由传输数据包.提出路由评估机制,建立了传输开销和传输效率的解析模型.解析结果显示,与NEMO基本支持协议相比,优化后的方案提高了数据包传输效率,更有效地利用了网络资源.

| Abstract: | According to network mobility(NEMO)specification proposed by IETF,the problems of sub-optimal routing and multiple encapsulations exist in nested mobile network,which will affect the performance of packet delivery efficiency.To solve this problem,a hierarchical based route optimization scheme(HRO)is proposed in this paper based on Hierarchical MIPv6(HMIPv6),the location management of mobile network nodes(MNN)was introduced;the routing path to transmits packets using MAP domain was optimized.Analysis models for route assessment,transmissions cost and delivery efficiency were also proposed,respectively.Analysis results indicated that the delivery efficiency is increased obviously,and network resources are utilized more effectively. |
