英文摘要：

A novel robust mobility management scheme （RMM） is proposed for hierarchical MIPv6. In RMM, the period of discovering the mobile anchor point （MAP） failure is decreased by adopting ICMPv6 protocol. And the procedure of recovering from the MAP failure is accelerated by using the primary and backup binding information. The performance of RMM is theoretically analyzed and com- pared with that of hierarchical MIPv6. The numeric and simulation results show that the performance of RMM is better than that of hierarchical MIPv6 in terms of MAP＇s reliability, packet loss rate and the period of discovery and recovery of the MAP failure.
