Inter-domain mobility support in Proxy Mobile IPv6 using overlap function of mobile access gateway

In this paper, we propose an inter-domain mobility support protocol in PMIPv6 networks using overlap function of Mobile Access Gateway. In the proposed protocol an MN maintain active communication sessions without mobility protocol stacks when the MN moves into another local mobility domain. Thus the proposed protocol retains the advantages of PMIPv6 for inter-domain mobility support. This protocol not only simplifies implementation and deployment, but also allows service providers to offer multi-services and communication ubiquity to customers with simple mobility hosts. We evaluate and compare network performance between our proposed solution and PMIPv6 and the main host-based mobility protocol, MIPv6 to demonstrate the advantages of proposed protocol.
