移动IPv6移动性能的改进

主要问题是移动IPv6协议中移动主机移动性能的改进。通过对现有方案的研究和分析，提出了一种新的多层次移动IPv6方案。新方案中采用了新的方法计算主机的移动速度以便移动主机选择合适的MAP，同时还提出了新的缓存机制来减少转交过程中数据包的丢失。还利用了NS2对新方案进行了模拟仿真。新方案可以适应移动主机的快速移动，并能够减少绑定更新报文和数据包的丢失。

Mobile IPv6 Mobility Improvement

This paper is about how to improve the mobile host's mobility. A fter the study of current schemes, this paper introduced a new Multilevel Hierarchical Mobile IPv6 scheme. The new scheme uses a new method to calculate the mobile host's speed so that the mobile host can select the proper MAP, and it also introduced a new cache mechanism to reduce packets lose during the handover period. The paper also used the NS2 to simulate the new protocol. The new scheme allows the mobile hosts to move fast, but the binding update messages and packets loss rate are reduced.
