Abstract

Location tracking and establishing end-to-end connectivity is one of the biggest challenges in mobile computing and wireless communication environment. Thus, there is a need to develop algorithms that can be easily implemented and used to solve a wide range of complex location management problems. Location management cost includes search cost and update cost. We have used reporting cells location management scheme to solve the location management problem. It has been reported that optimal reporting cell configuration is an NP complete problem. In the reporting cell location management scheme, few cells in the network are designated as reporting cells; mobile terminals update their positions (location update) upon entering one of these reporting cells. Vicinity of a reporting cell is defined as the number of reachable cells, without going through any other reporting cell. The objective of this paper is to minimize the location management cost of the network through an optimum reporting cell configuration. The proposed approach is giving better performance for bigger networks compared to earlier schemes. We also show the change in the location management cost with respect to different calls per mobility values and network size.
