Mobile IPv6 (MIPv6) is extended to Hierarchical MIPv6 (HMIPv6) by introducing a Mobile Anchor Point (MAP) between home agent (HA) and the mobile node’s (MN’s) temporary location. The MAP acts as a coordinator of the MN and reduces signaling cost for handoff management. It also reduces handoff latency suffered by MN. However, the MAP in the HMIPv6 architecture is a single point of failure, as all packets from any correspondent node (CN) goes via the MAP. In this paper, a thorough analysis of the MAP performance in terms of packet loss probability, packet blocking probability and end-to-end delay is presented. Three classes of users, namely Thin, Normal and Fat, are identified based on the amount of packets transmitted per second by the user. From the analysis carried out in this paper, we wanted to examine the volume users in different classes, i.e., Thin, Normal and Fat that can be supported by a single MAP under its coverage without deteriorating the quality of service (QoS) to the end users. A scheme for selecting an alternative MAP by an MN (MAP selection algorithm) is proposed here in order to preserve the QoS to the end users under the circumstances when the current MAP is unable to satisfy the need of the newly arriving MN. The proposed algorithm named as User-Centric MAP Selection (UCMS) is compared with existing similar protocol, Adaptive Overload Prevention (AOP). Observation shows that UCMS performs better in selecting a new MAP.
