An Efficient Correspondent Registration to Reduce Signaling Overheads for Proxy Mobile IPv6

This paper proposes an efficient correspondent registration mechanism to reduce the signaling overhead for the Proxy Mobile IPv6 (PMIPv6). In the proposed mechanism, the signaling overhead for the proxy home test via Local Mobility Anchor (LMA) is eliminated in case of refreshments for the correspondent registration. Therefore, through the proposed mechanism, the burden of tunnels between Mobility Access Gateways (MAGs) and LMA as well as LMA can be lessened. The performance of the proposed mechanism is analytically computed and simulated in view of the signaling overhead, which shows the proposed mechanism can enhance the existing mechanism.
