Research On Multi-Gateway Routing Measurement For Ad Hoc Network Based On IPv6

With the development of information technology, wireless local area network (WLAN) are found everywhere in our lives. The demand for mobile communication is growing and the requirements for communication capabilities of the mobile terminals have become higher and higher. In order to ensure a variety of mobile devices for a smooth migration from one network to another, we have designed various network architectures and routing protocols, among which the Ad Hoc network has been adopted more and more widely. No matter as a terminal access in daily life or as an Internet of Things communication, it can provide various adaptive solutions. With the promotion of IPv6protocol, the address digit upgrade has a great effect on the Ad hoc networks which is non-center structure. The combination of multi-node routing communication and IPv6protocol has generated a host of new problems in both network lays and transport layer.The main work of this thesis is as follows:on the basis of in-depth understanding of the current Ad Hoc network researches, a variety of different Ad hoc network routing protocols were analysized and compared. The multiple gateway access was proposed, and the partial functions of AODV routing protocol are optimized, and the new message-grouping was formatted to realize the gateway declaration。Supporting of multiple gateway interconnection scheme between mobile Ad hoc network and Internet based on IPv6occurred. The comparison between two typical routing protocols was made in NS2simulation platform in a Linux environment. The scope of the IPv6-based Internet mobile access was further expanded to upgrade AODV to AODV in NS2AODV to AODV6. The ideas were simulated and verified.
