摘要
移动IP技术使移动节点可以用一个永久的IP地址连接到任何链路上,但是也带来了三角路由的问题。路由问题一直是研究的热点,但是目前仍未能很好地解决。介绍了移动IP的工作原理、"三角路由"的成因,对移动IP技术中的几种路由方案进行了分析研究,提出了一种改进方案,并引入了安全机制。该方案较好地解决了三角路由和移动节点频繁切换所带来的延时问题。
Mobile IP technique can make a mobile node link any network by using the permanent IP address,but this technique brings the triangle routing problem. As a focus of study the routing problem has not been well solved yet. This paper introduces the working mechanism of mobile IP and the cause of the triangle routing. After analyzing several routing schemes in current mobile IP technique, an improved scheme was proposed which imported the security mechanism. The scheme overcomes the triangle routing problem and the handoff delay problem.
