Abstract:

Aiming at decreasing of binding update cost and data transfer cost of proxy mobile Internet protocol version 6 (PMIPv6) network, the concept of integrated optimization is adopted. Comparing the cost of PMIPv6 with MIPv6, the decision function used to determine when PMIPv6 is adopted preferably is obtained, and the adaptive mobility management scheme is proposed, that allows a mobile node (MN) residing in a PMIPv6 domain to select a suitable mobility management dynamically from PMIPv6 and MIPv6 according to its working parameters. Simulation shows that the proposed scheme will have good utilization of resources.

Key words: proxy mobile Internet protocol version 6, management cost, adaptive optimization
