【Abstract】 As a micro mobility approach,Hierarchical Mobile IPv6 (HMIPv6) has been designed to improve the performance of Mobile IPv6 (MIPv6) on the number of management messages and handoff latency.Aiming at decreasing transfer cost and bandwidth consumption when enhancing the mobility management of Internet,the concept of integrated optimization is adopted in this paper.After theoretical computing and comparing the cost of HMIPv6 with MIPv6’s,the judgment rules used to determine when HMIPv6 is adopted preferably are obtained,and Adaptive Mobility Management Scheme (AMMS) is proposed,which allows a mobile node residing in a HMIPv6 domain to select a suitable mobility management dynamically from MIPv6 and HMIPv6 according to its working parameters.The results of simulation show the expected performance.更多还原
