A cell-based location-sensing method for wireless networks

One of the most important applications for mobile commerce is location-based application and the core technology of location-based applications is the location-determination technology. In this paper, we present a location-sensing method, called cell-based location-sensing method and its positioning accuracy for the wireless networks with hexagonal structure and mesh structure. In addition, the accuracy of the method is optimized by tuning the transmitting power of base stations. In the optimal transmitting power, an accuracy of within 9.1667% (7.2182%) cell area for hexagonal structure (mesh structure) can be achieved by the cell-based location-sensing method. We believe that the results are useful for deploying wireless networks for location-based applications. Copyright  2003 John Wiley & Sons, Ltd.
