CENTRAL ISSUES AND CLASSIFICATIONS OF LOCATION MANAGEMENT TECHNIQUES IN WIRELESS AND MOBILE COMPUTING SYSTEMS
Seung-Yun Kim, Waleed W. Smari · 2003
The rapid growth in mobile and wireless computing technology continuous to present new challenges. Mobile users access information, independent of their location, through wireless and wired networks. In mobile computing, location management is introduced whenever users move from one place to another. In order to track a mobile user, the system must store information about his current location and report new locations to a home base station. Several techniques have been proposed to optimally manage the location of mobile hosts. In this paper, we present an overview of some principal issues, concepts and definitions used, and techniques proposed and developed for location management in mobile computing systems. The performance of these techniques is dependent on several parameters, such as the Call-to-Mobility Ratio (CMR). It also depends on update and routing costs, calls, and moves. We discuss different approaches introduced and assess their effectiveness. This will be followed by a survey of existing classifications of location management solutions. Finally, we introduce an alternative way of classifying these techniques in light of the central issues identified and in order to facilitate the development and design of a framework for these systems.
