移动IP切换性能研究
摘要
传统Internet由于时空上的限制,不能满足越来越多移动用户的需求,因此一种新的技术——移动IP技术,应运而生。让移动用户能够在自己所处的位置不断变化的情况下,保持已有的通信连接。
移动IP切换是移动IP技术的一个关键问题,切换性能的优劣直接关系到通信质量的好坏,对移动IP切换研究是移动IP技术研究的一个热点,能否提供一种高效的低丢包率、低切换延迟的切换算法是亟待解决的问题。
针对移动IP切换性能问题,本文重点提出一种移动IP切换参数检测模型,对模型进行仿真,通过仿真分析移动IP切换性能。从优化链路层切换角度考虑减小移动IP切换延迟,提出一种移动IP在无线局域网下的改进切换方案。
全文主要内容如下:
(1)对移动IP基本原理进行研究,深入学习和总结现有各种移动IP切换技术,对影响移动IP切换性能的各种因素进行深入分析。
(2)提出一种移动IP切换参数检测模型,通过模型分析切换延迟、数据包丢失和分组乱序情况。通过仿真追踪TCP数据包,分析移动IP切换过程和移动性对移动IP切换性能的影响。
(3)当移动节点在两个不同子网之间发生移动IP的切换时,将先后进行链路层切换和网络层切换。从网络层切换角度考虑,或多或少要改变现有移动IP规范。因此,我们从链路层切换角度考虑,提出一种移动IP在无线局域网下的一种改进切换方案。该方案较好的减小移动IP切换延迟,提高移动IP切换性能。
The traditional Internet because of the restrictions on space and time, it can't satisfy with more and more mobile users' requirements, so a new technology——mobile IP technology emerges as the times require. For mobile users maintain the existing communication links in the ever-changing circumstances.
The mobile IP handoff is a key issue of mobile IP technology, the pros and cons of handoff performance directly related to communication quality is good or bad, Mobile IP handoff technology research is a hot research, the ability to provide an efficient and low packet loss rate, low handoff latency algorithm is the urgent need to resolve the issue.
As to mobile IP handoff performance issues,this paper presents a mobile IP handoff parameter detection model,simulates the model,and analyzes Mobile IP handoff performance through simulation. From the point of optimizing link layer handoff to decrease mobile IP handoff latency,we present a improving scheme of mobile IP in wireless LAN.
The main contents of this paper are as following:
(1) Study the basic mechanism of mobile IP,deep study and summarize the present mobile IP handoff technology,analyze the various factors of impacting mobile IP handoff performance.
(2) Present a mobile handoff parameter detection model,analyze the case of handoff latency、packet loss and packet disorder. Track TCP packet to analyze mobile IP handoff process and mobile IP handoff performance under moving.
(3) When the mobile nodes occur handoff from one subnet to another subnet,will be to link layer handoff and network layer handoff. From the network layer handoff point of view,more or less to change the present mobile IP standard. Therefore,we present a improving scheme of mobile IP in wireless LAN from the point of optimizing link layer handoff. The scheme reduces mobile IP handoff latency better, advances mobile IP handoff performance.
