Fast Handover Scheme Based on Mobility Management of Head MAG in PMIPv6

Proxy Mobile IPv6 (PMIPv6) is a network-based mobility management protocol that supports network mobility, regardless of whether or not a Mobile Node (MN) supports mobility protocol, such as Mobile IPv6 (MIPv6) and Hierarchical MIPv6 (HMIPv6). However, PMIPv6 protocol does not consider the packet loss during MN's handover. We propose a fast handover scheme using the Head Mobile Access Gateway (MAG) to provide a fast and seamless handover service in PMIPv6. The proposed scheme does not violate the principle of PMIPv6 by maintaining mobility information of the MN in the Head MAG. The Head MAG is granted to an MAG deployed at an optimal location in a Local Mobility Anchor (LMA) domain. The Head MAG reduces packet loss and enables fast handover by providing mobility information of the MN to the MAGs in the same LMA domain. In this paper, we analyze an analytic performance evaluation in terms of signaling cost and size of packet loss. The analytic performance evaluation shows that the proposed scheme is compared with basic PMIPv6 and the previous proposed scheme using the Neighbor Detection (ND) message. The proposed scheme reduces signaling cost by over 30% compared to the previous proposed scheme using ND message and packet loss by over 78% compared to basic the PMIPv6 scheme.
