Reducing dogleg routing in mobile IPv6 by the enhancement of home agents deployment

摘要

Mobile IPv6 (MIPv6) was developed by the Internet Engineering Task Force to support the mobility service as wireless technologies have grown and many people are more and more using wireless networks during movements. MIPv6 has long been favored over Mobile IPv4 and it's a major solution to supply mobility services on the Internet and therefore it's proposed for the future of the mobile Internet access. Many networking vendors have already implemented it in their operating systems and equipments even if, in practice, vendors are actively deploying these capabilities only in part. Moreover, MIPv6 was recently selected to provide network-level mobility management to end-users of WiMAX and 3GPP2. The aim of MIPv6 is to provide uninterrupted connection while users being mobile. This protocol relies on a specific router called the home agent that hides location changes of the mobile nodes from the rest of the Internet. To do so, the mobile nodes traffic must flow through the home agent. This mandatory deviation, called dogleg routing, produces longer paths and higher communication delays. Therefore, MIPv6 cannot satisfy requirements of realtime applications such as video streaming service and VoIP service. In order to solve these problems, we intend to develop a new approach to address deployments of Home Agents in MIPv6 based on mobility patterns.
