Analytical Modeling of IP-based Hierarchical Mobility Management Protocols

Cost-effective mobility management for roaming mobile users is very important in providing seamless service on next-generation wireless networks (NGWNs). Various IPv6-based mobility management schemes have been developed which are directly involved with data transfer from Mobile Node (MN). In this paper, two methods for analyzing mobility management schemes are proposed and the signaling transfer and packet delivery procedures for each mobility management scheme are analyzed. The signaling costs of the mobility management schemes are calculated, and the cost of each protocol is analyzed numerically. Our performance evaluation results revealed that the network-based mobility management scheme yields better performance in terms of overall cost.
