摘要：Most existing mobility management deployments such as MIPv6, PMIPv6 and 3GPP utilize centralized mobility anchors in the hierarchical network architecture. Centralized mobility schemes are subject to restrictions on reliability of SPOF (Single Point Of Failure) and network scalability, etc. As an alternative to the centralized approaches, DMM (Distributed Mobility Management) mechanisms have been actively and widely studied these days. In DMM, functions of the anchor node are efficiently distributed to access routers. This paper suggests the network-based partially distributed mobility management mechanism and performs extensive simulations under various traffic environments for verification and evaluation of the suggested scheme. Performance indexes such as Tx/Rx UDP traffic, end-to- end data transfer delay, binding delay, CPU utilization, WLAN throughput are analyzed and compared among MIPv6, PMIPv6 and the suggested DMM scheme. Simulation results show that the DMM scheme suggested in this paper is useful for IP mobility management research in wireless environment.
