New User Tracking Algorithms for a Wireless Network and Performance Analysis

| In cellular wireless networks, paging and user location update are used to deliver calls to mobile users. We propose two new user location update methods. One method which improves the movement based user location update scheme, exploits the locality of user movement patterns. Another method performs distance-based location update based on LA such that it simpliies implementation. To compare the performance of these proposed methods with that of existing methods, we develop an analytic model and carry out the performance comparison. The results show that the proposed methods improve the performance of existing methods significantly .
