Scalable Local Mobility Support for the IPv6-Based Wireless Network Using Improved Host Based Routing
There have been active research activities to solve the problems of frequent handoff and encapsulation overhead in the 3G or 4G wireless IP networks. The host based routing scheme has been proposed to provide the micro-mobility management. One of the drawbacks of the host based routing scheme is the limitation in scalability. Accordingly, the current paper presents a new host-based routing scheme that improves the scalability, while providing a fast handoff and various efficient forwarding schemes. Furthermore, it is compatible with the basic Mobile IPv6 protocol. When applied to the HAWAII protocol in an IPv6 network, the new scheme eliminates the limitations of the legacy micro-mobility protocols by providing both a seamless and transparent service and a fast and smooth handoff. A performance evaluation is done to show the scalability improvement.
