In this paper, we propose a mobility-based prediction algorithm with dynamic LGD (Link Going Down) triggering for vertical handover by applying the IS (Information Server) of IEEE 802.21 MIH (Media Independent Handover). The proposed algorithm predicts a possible moving area (PMA) of the mobile terminal based on mobility information (the velocity, coordinate values, position, movement detection, etc) in IS. Since the PMA indicates a next target cell for handover, it can advance the LGD trigger point dynamically to prepare for handover beforehand. The analytical results show that our prediction algorithm can reduce handover latency for MIPv6 (Mobile IPv6), FMIPv6 (Fast Handover for Mobile IPv6) by advancing the LGD trigger point.
