Minimizing the Wireless Cost of Tracking Mobile Users: An Adaptive Threshold Scheme
Mobile user tracking is a major issue in wireless networks. Previous studies and traditional approaches dealt only with tracking algorithms which adapt themselves to the user activity. In this work we propose a novel approach for user tracking, in which the tracking activity is adapted to both user and system activity. The basic idea is to make the user location update rate dependent not only o...
متن کاملTracking mobile users
Cellular telephony systems, where locations of a mobile users may be unknown at some times, are becoming more common. Mobile users are roaming in a zone. A user reports its location only if it leaves the zone entirely. We consider cellular zones with n cells and m mobile users roaming among the cells. The location of the users is uncertain and is given by m probability distribution vectors. The...
متن کاملCell Identification Codes for Tracking Mobile Users
The minimization of the wireless cost of tracking mobile users is a crucial issue in wireless networks. Some of the previous strategies addressing this issue leave an open gap, by requiring the use of information that is not generally available to the user (for example, the distance traveled by the user). For this reason, both the implementation of some of these strategies and the performance c...

متن کاملA Noble Fuzzy-based Mobile Tracking Scheme
(PSS), the distance between the mobile and the base station, the moving direction, and the previous location are used in the decision process using the aggregation function in fuzzy set theory. In the microcell-or picocell-based system the frequent movements of the mobile bring about excessive traffics into the networks. A mobile location estimation mechanism can facilitate both efficient resou...
