Since a cell size will be smaller and Mobile IP users are expected to grow in the next mobile network, micro mobility occurs more frequently. In IP micro mobility environments, the wireless link has far less available bandwidth resources and limited scalability compared to the wired network. Therefore, the signaling overhead associated with mobility management has a severe effect on the wireless link. In this paper, we propose the Virtual-IP (VIP) Zone algorithm. In the proposed algorithm, Access Routers (ARs) with a large rate of handoff are allocated into a VIP Zone. The signaling overhead in the wireless link can be greatly reduced as the current Care-of Address (CoA) of Mobile Node (MNs) is not changed whenever the handoffs occur between ARs within the same VIP Zone. We present the performance evaluation for VIP Zone algorithm and HMIPv6. As a result, we present various simulation results in different environments.
