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

In a single local mobility domain of Proxy Mobile IPv6 (PMIPv6) the mobile node (MN) uses only its PMIPv6 home address for all its communication. When the MN moves into another domain, the MN must change its PMIPv6 home address and host-based mobility signaling is activated. Consequently PMIPv6’s network-based mobility cannot be retained. Additionally, if the MN does not support inter-domain mobility, it cannot maintain its communication sessions with its correspondent node (CN). In this paper, we propose a inter-domain mobility support protocol in PMIPv6 networks using overlap function of mobile access gateway called overlap-MAG. In overlap-MAG protocol an MN maintain active communication sessions without mobility protocol stacks when the MN moves into another local mobility domain. Thus, overlap-MAG protocol retains the advantages of PMIPv6 for inter-domain mobility support. However only a few modifications are necessary on the mobile access gateway without any modifications of MN and CN’s protocol stacks. Thus, overlap-MAG 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.
