PMIPv6 Route Optimization Mechanism Using the Routing Table of MAG

The IETF is specifying mobility management protocols. Recently, proxy mobile IPv6 has been specified as a network-based localized mobility management protocol. Since the base specification of proxy mobile IPv6 does not cover the route optimization, many research papers have been suggested for route optimization in proxy mobile IPv6. However, most of suggestions are concentrated on the route optimization between two mobile nodes that follows proxy mobile IPv6 operations. In this paper, we propose a new mechanism for route optimization between proxy mobile IPv6 based mobile node and on-link IPv6 prefix based node within proxy mobile IPv6 domain. The proposed mechanism uses the routing table and security policy database of the mobile access gateway to find the optimized route between them. We analyze our proposed mechanism in mathematical method and discuss the enhancement of the performance as well as the effect of the environmental parameters.
