Location management is the most important function in mobility management technology. The hierarchical structure of the proposed hierarchical network-layer mobility manage- ment (HNMM) can reduce the signaling cost. The self- organizing 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.
