A Novel Scheme for Efficient Interworking with MIPv6 Hosts in the PMIPv6 Network

In this paper, we propose a novel MAS algorithm to reduce the amount of signaling and data traffics. To notify an MIPv6 host of the proposed operation, we design a new binding registration function into the MAG, and suggest the modified RS and RA messages. The binding registration in the MAG instead of the LMA is accomplished to support the PMIPv6, whereas a 1-bit N flag in the RS and RA message indicates where the MAG supports the PMIPv6 or not. Our proposed algorithm has the advantage for MIPv6 hosts in the PMIPv6 network in the viewpoints of network utilization and performance. To show the verification and better performance of the MAS algorithm, we evaluate the amount of traffic and its related performance, and compares those with performance of the normal PMIPv6. These results show that our proposed algorithm can operate efficiently and give better performance for MIPv6 hosts in the PMIPv6 network.
