一种基于缓冲的分层次移动IP模型——BHMIP

BHMIP:A BUFFER BASED HIERARCHICAL MODEL FOR MOBILE IP

现有的移动IP方案在网络切换时存在着切换时延过大和丢包率过大两个问题,已提出的快速切换方案(fast handover)和分层次的IP方案(HMIP)针对切换时延和注册信令开销过大进行了一定的改进。BHMIP方案在HMIP和快速切换的基础上结合缓冲机制对切换过程中丢包率过大的问题进行了改进,并通过模拟仿真进行了验证。最后指出了进一步的研究方向。

The two significant problems existing in the current Mobile IP are problems of handover latency and packets loss. Some schemes such as fast handover and HMIP have been proposed to solve these problems. They have made some improvement in handover latency and problem of register messages. A new model called BHMIP based on HMIP, fast handover and buffer scheme is proposed. It makes much improvement in the problem of packets loss during handover. The BHMIP scheme is verified through ns-2 simulation. Finally ,the further research direction is pointed out.
