The Cost effective Location Management Scheme using Mobility Information and Received Signal Strength of Mobile Users in Wireless Mobile Networks

Recent advances in cellular mobile communications have touched every aspect of our lives. In mobile computing, mobile hosts or mobile terminals (MTs) move randomly from one place to another within a well-defined geographical area. To provide timely services to mobile users, a challenging task is to track the location of the mobile user effectively so that the connection establishment delay is low. This can be done only if available system resources are used optimally. In most of the available schemes, when a call arrives, the target MT is searched using a method calledpaging even when the target MT is in such a low coverage area where it can not bear a call. This wastage of network resources puts extra burden on the network and increases the total location management (LM) cost. The proposed scheme tries to cut off this resource wastage up to a significant amount by not paging those MTs that can not bear a call due to low received signal strength (RSS) value. The performance of proposed scheme is evaluated using an analytical model and is compared with Sun-Jin-Oh´s LM scheme[1].
