A Local Anchor Scheme for Mobile IP

Abstract

The Mobile IP protocol requires that the mobile computer registers with its home agent through the foreign agent whenever it moves into a new serving domain. If the mobile is far away from its home network, the signaling cost cannot be ignored and the long registration delay would introduce extra traffic cost. The local anchor scheme defines a two-tier registration procedure. When the mobile moves within the coverage of the current anchor, it only needs to register with the current anchor, rather than with its home agent. Thus, the frequency that the mobile needs to register with its home agent is effectively reduced. Comparisons on handoff delays, TCP/UDP costs, and TCP throughput show that the local anchor- based Mobile IP scheme exhibits superior performance over the regular Mobile IP scheme.
