Performance Analysis of a Protocol for Network-Based Localized Mobility Management

摘要

This paper introduces a protocol for network-based localized mobility management solution, and develops an analytic model for the performance analysis based on one-dimensional random walk of mobile node. Based on the analytic models, the location update cost and the packet delivery cost are formulated. Then, the impacts of average cell residence time and the number of mobile nodes in a cell on the total cost are analyzed, respectively. In addition, the variation of the total cost is studied as the session-to-mobility ratio is changed and the optimal local mobility domain size to minimize the total cost is also investigated. The analysis results indicate that the session-to-mobility ratio and the local mobility domain size are critical performance factors in order to minimize the total cost.
