Study And Implementation Of A Fast Link Setup Method In Mobile IP Communication Network Based On Mobile Agent

Mobile communication and Internet have become the fastest developing, most potential and attractive two communication systems since the end of 20th century. mobile IP technology,which combines these two technologise, has promising future.This thesis proposes a fast link setup method in mobile IP communications, which could smooth the high speed switch in ramble process by optimizing routing.It could also resolve the"triangle routing problem"in present mobile IP network.First of all, this thesis introduces some relative technologies, analyses their development and application situation in mobile agent system. Then it proposes the solution or optimization scheme focusing on problems of these technologies coming out in the applications.This thesis also shows deep reseach work on mobile agent technology and Dijkstra algorithm. Furthermore, it analyses their characteristics and amalgamation with mobile IP technology.And then, a novel communicating links establishmen method with mobile agent unit when switchs from cell to cell occur is proposed. Along with an innovative new mode of dynamicly self-adapting routing is presented. The combination of those two methods could reduce the delay to 27 - 41 percents in switch, and the system package losing could reduce to 29 percents averagely.Finially, the realization details and the key flow chart, software codes of these novel methods are shown. Through simulation and tests on simulation platform, the efficiency of the novel method is verified.
