Reducing the cost of dynamic mobility management in wireless communication networks has been an interesting and important issue. It is well known that by using a selective paging method, both costs for location update and terminal paging can be reduced significantly. However, an efficient selective paging method needs the information of the location distribution of a mobile terminal. Based on o...

Managing location information of mobile agents (MAs) is an important issue in MA based mobile computing systems. There is a tradeoff between location update effort (when an agent moves) and agent finding effort. In this paper we present a dynamic location management strategy that has the following features: (i) all location servers (LSs) need not maintain location information of every MA, (ii) ...

Cellular communication allows subscribers to make and receive calls from anywhere. In the USA, cellular communication was fi rst deployed at the 800MHz band. In order to accommodate more subscribers, the FCC (Federal Communications Commission) allocated the 1900MHz band for PCSs. PCS uses a cellular network as its infrastructure. In a cellular network, a service coverage area is divided into sm...

Location management is very important in location-based services to provide services to the mobile users like banking, city guides and many more. Ubiquitous and mobile devices are the source of data in location management and its significant operations are update and search method. Some studies to improve these were presented by using optimal sequential paging, location area scheme and hierarch...

Managing location information of mobile devices is a very much important task in mobile computing systems. In cellular network, coverage area is divided into cells. Everyday mobile companies try to accommodate more users by reducing size of cells. Location management is one of the most important and fundamental issue in mobile computing. When the user changes location, an update occurs. The mai...

This paper introduces a location-based locating strategy for Personal Communication Services (PCS) systems. In the proposed scheme, location updates are based on the value of a movement counter. The update of the movement counter is based on information on the locations visited by a mobile terminal (MT) since the last location update. In particular, the cell identi®ers and the corresponding mov...

General Packet Radio Service (GPRS) is a complex data network which upgrades current second generation GSM networks, offering true high-speed internet (IP) and network connectivity over existing GSM cellular networks. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. This project deals wit...

In this paper we propose an efficient location management strategy called the profile-based two-level pointer forwarding cache scheme to improve the overall performance of the wireless mobile networks. It uses the two-level pointer for location update and the profile-based cache for call delivery. Location update for each Mobile Terminal (MT) is managed by the nearby Visitor Location Register (...
