Hierarchical Mipv6 Mobile Ad Hoc Network Management Research

As the IPv6's rich address resource, internal security and mobility, IPv6 will necessarily replace IPv4 as the next generation internet protocol. The Ad Hoc Networks have been applied in many environments for the advantage of networking flexibility and distributed control.The combination of mobile IPv6 and Ad Hoc Networks has two advantages: on one hand, using the mobile management technology of mobile IPv6 to achieve mobile switching; on the other hand, using the networking flexibility and a greater communication range of Ad Hoc Networks to build an all IP networks quickly. Therefore, the combination of mobile IPv6 and Ad Hoc networks will be applied more and more in the future, and the study of mobile IPv6 based on Ad Hoc networks will also become increasingly important. However, the mobile IPv6 are targeted at single-hop networks having AP, Ad Hoc networks have no AP and mutli-hop is the most import trait. Therefore, for the adopting of mobile IPv6, the Ad Hoc networks needs to be improved in some aspect. The main content of this paper is to establish IPv6-based mobile Ad Hoc network, and through simulation and implement under Linux to analysis and improve.This paper firstly introduced the background knowledge of Ad Hoc network; theoretically analyzed the switching process of mobile IPv6 in any period; and proposed mobile IPv6 switching based on credible-zone for the ping-pong movement.Secondly, the paper proposed the Ad Hoc network of basing on mobile IPv6 and made improving scheme; then adopted OPNET to simulate the scheme of fast-address configuration,the optimization scheme of router to forward notice based on MRP mechanism,the mobile IPv6 switching based on credible-zone and the hierarchical Ad Hoc network based on mobile IPv6 as well as analyzed the delay of any switching period;Finally, the paper introduced the Linux implement platform and the implement program of mobile IPv6; and through modified the source code of iwlist tool to generate new link layer scan and auto-switching program; at last built Ad Hoc network model to test and analyze switching delay indoor and outdoor.
