Ip Mobility Extensions. Micro-mobility Protocols And Simulation

At present, the scale of Internet is unceasingly expanding at an astonishing speed, while the mobile communication is also in rapid progresses in leaps and bounds. More and more mobile subscribers hope that turning on Internet more easily, and without space and time limit. Mobile IP technology is precisely this kind of technology interconnecting mobile subscribers and the Internet, and it can make the mobile subscribers need not to change their IP addresses to maintain the Internet correspondence which carries on while they move here and there. Therefore Mobile IP becomes the current hot research topic.This article elaborates "Mobile IP" which is product of the mobile communication network and the Internet agreement combination. The paper' s first part is the elaboration on the Mobile IP research background, and then researches in details including researches on Mobile IP entirely in the mobile communication network important status, the careful theory description to IP technology and the network protocol theory, the analysis network protocol and the function, the meaning and the application of Mobile IP, the TCP/IP agreement model analysis, IP network QOS technology and the security challenge Mobile IP faces analysis. From the angle of mobilized wireless network, and the agreement, principle and the realization mechanism of Mobile IP, the research analyzes domestically proposed under four kind of micro migrations Mobile IP the cut management expansion plan: The honeycomb IP plan, the HAWAII plan, the TeIeMIP plan and the EMA plan, and to moved IP to four kind of micro migrations under the cut management expansion plan key technologies to carry on the comparison and the appraisal have carried on the comparison, expounding respective good and bad points. It will be advantageous for from now on through the expansion plan confirmation, the implementation and the optimization create the condition for the second generation of mobile communication entire IP core network gradually establishment. Finally it carried on the cut mechanism improvement simulation confirmation under the micro motion condition, with the aid of each kind of mature simulation tool to the improvement program. Through analysis on the result, proved plan can be improvable to QoS at a certain extent.
