An Enchanced MAG Forwarding Scheme for Proxy Mobile IPv6

Long registration delay and signaling cost restrict the practical deployment of MIP. Proxy Mobile IPv6 has been proposed to overcome limitation of Mobile IP, which can avoid tunneling overhead and support of hosts in the mobility management. In this paper, we propose an extension protocol based on Proxy Mobile IPv6 to reduce the overhead of Local Mobile Anchor and decrease handoff delay. When the MN is moving in a Registration Area(RA), current MAG directly sends redirection message to Primary MAG avoiding remote signaling cost to LMA. Analysis results demonstrate that our extension scheme reduces the overhead by decreasing the network signaling cost and optimizes handoff capability.
