Location Management Strategies for Reducing Both Movement Cost and Locating Cost Simultaneously

摘要

A major problem in a wireless communication system is how to locate mobile clients. This is named the location management issues. Two major operations are involved in managing a mobile client's location: the movement, operation and the locating operation. The past methods can only minimize the cost of one of these two operations, but not both. The major contribution of this paper is to propose strategies that minimize the costs of both operations simultaneously. Our performance analysis proves that the proposed strategies are superior to the past methods.
