中文摘要：

地点管理是在活动性管理技术的最重要的功能。建议层次网络层活动性管理(HNMM ) 的层次结构能减少发信号的费用。自我组织的拓扑学计划能提高活动性管理的坚韧性和质量。活动节点的地点的信息在分布式的数据库被存储，它做更可靠、柔韧的地点信息的存储，并且更灵活的策略能被使用。数字结果证明 HNMMcan 比活动 IPv6 的一般结构提供更好的性能，当活动节点经常移动时并且当有高交通的产量时。

英文摘要：

Location management is the most important function in mobility management technology. The hierarchical structure of the proposed hierarchical network-layer mobility management （HNMM） can reduce the signaling cost. The selforganizing topology scheme can enhance the robustness and quality of the mobility management. The information of location of the mobile node is stored in the distributed database, which makes the storage of the location information more reliable and robust, and more flexible strategies can be used. The numeric results show that HNMM can provide better performance than the general structure of mobile IPv6, when the mobile nodes move frequently and when there is high traffic throughput.
