Predictive direction location update scheme for next generation PCS networks

Abstract

We consider the problem of locating mobile users in wireless networks with the focus on minimizing the overall cost incurred by the two main activities involved, mainly lookup and update. We propose a location update protocol that relies on the deployment of prediction techniques along with the Direction Based Update algorithm. The proposed protocol is implemented over both random walk and random waypoint mobility patterns. The results obtained proved a reduction in the overall cost up to 47% compared to the direction based location update scheme with line paging for random waypoint mobility pattern.
