An Efficient Mobility Management Scheme for Hierarchical Mobile IPv6 Networks

Abstract

Performance evaluation shows that Hierarchical Mobile IPv6 (HMIPv6) cannot outperform standard Mobile IPv6 (MIPv6) in all scenarios. Thus, adaptive protocol selection under certain circumstances is desired. Moreover, the registration cost of HMIPv6 needs to be reduced further. However, the performance of existing mobility based schemes is limited because they all neglected the traffic parameter of the mobile node (MN). In this paper, we propose an efficient three-level hierarchical architecture for HMIPv6 networks, in which an MN may register with either a higher/lower Mobility Anchor Point (MAP) or its home agent. By analyzing the inter-domain registration cost function, we obtain a novel parameter for MAP selection, which takes both the mobility parameter and the traffic parameter of an MN into account to minimize the overall registration cost. Simulation results show that normally the novel MAP selection algorithm achieves 25% percentage reduction of registration cost over the traditional mobility based algorithm. In addition, this algorithm obtains better performance when the mobility parameter and the traffic parameter of the MN vary.
