Abstract

State-of-the-art wireless communication networks allow dynamic relocation of mobile terminals. A location management mechanism is required to keep track of a mobile terminal for delivering incoming calls. In this paper, we propose a fuzzy logic-based location management method to reduce paging cost. In the proposed method, the location update uses an area-based method that uses direction-based method together with movement-based method, and the location search uses a fuzzy logic-based selective paging method based on the mobility information of mobile terminals. A partial candidate paging area is selected by fuzzy control rules, and then the fuzzy logic-based selective paging method pages only cells within the partial candidate paging area. The performance of the proposed fuzzy logic-based location management method is evaluated by an analytical model and by a simulation, and is compared with that of basic velocity paging (BVP) method.
