Hierarchical Mobile IPv6 (HMIPv6) was proposed by Internet Engineering Task Force (IETF) to reduce signalling cost by localising the mobility signalling traffic of Mobile Nodes (MNs). However, certain MNs still generate excessive signalling overhead, due to their ping pong movement at borders of different Mobility Anchor Point (MAP) domains. In this paper, an algorithm is proposed, to effectively reduce the handover signalling overhead in the network. A cost function was developed and allocated to Access Routers (ARs) in then network, by taking into account several parameters.
