Research on All IP Wireless Network Mobility under Micro Mobility Protocol
IP micro-mobility is one of the mobility management methods that can improve the communication quality during movement of mobile nodes. Handoff management is the key technology. Analyzes the disadvantages of micro-IP protocols and IP network, most concern problem of allIP wireless network mobility are set out in details, describes a mainstream regional mobility management protocol PMIPv6, analyzes its switching mobility management mechanisms within the domain. Concludes an optimization method based on network proxy mobility management within the switch management, and with formation of IETF standard performance analysis and comparison of the methods, prove that the method can be effective in reducing switch delay and location updating signal costs.
