The majority of research on MIPv6 only considers the mobility of nodes. However, using MIPv6 for mobile network will introduce a problem such as dog-leg routing. A mobile network is composed with one or more visited mobile networks as well as mobile nodes in fixed network environment. In order to communicate from foreign network with mobile nodes, packets are usually transmitted via the home link of the mobile node. This introduces a dog-leg routing. Especially, the increasing number of visited mobile network may cause a transmission delay for the packet. Dog-leg routing may cause a transmission latency, this subsequently causes the difficulty for a real time service and the delay in binding update. Our research tries to solve the dog-leg routing by only expanding AR (access router), MR (mobile router), HA (home agent) of MR without any changes in MN, HA of MN and CN. The second part of my research outlines the performance which reduces binding update latency and the number of binding update message through regional registration.
