A mobile-node-assisted localized mobility support scheme for IPv6

As the number of portable devices roaming across the Internet increases, the problem of routing packets to mobile hosts generates increasing research and commercial interest. This paper presents a mobile-node-assisted scheme to support localized mobility in the Internet in a distributed fashion. In the proposed scheme, a mobile node is enhanced to utilize an access router in a foreign domain as an anchor point in the domain. On the other hand, entities in the network-side are only required to provide Mobile IPv6 functionalities in this scheme. Our scheme has three main benefits; reducing the load on the backbone of the Internet, scalability, and interoperability.
