We propose an integrated location management and location-aided routing system which organizes the Mobile Ad-hoc Network (MANET) into a two-level hierarchy with the help of Voronoi diagrams. The location information of mobile nodes in a Voronoi zone is summarized using Bloom Filters and distributed among the location servers in the zones. The integrated system has the property that the destinat...

An important issue in location management for dealing with user mobility in wireless networks is to reduce the cost associated with location updates and searches. The former operation occurs when a mobile user moves to a new location registration area and the network is being informed of the mobile user's current location; the latter operation occurs when there is a call for the mobile user and...

Location management is important to effectively keep track of mobile terminals with reduced signal flows and database queries. Even though dynamic location management strategies are known to show good performance, we in this paper consider the static location management strategy which is easy to implement. A system with single home location register and pointer forwarding is assumed. A mobile t...

Location management is one of the most important aspects in the realization of mobility in wireless networks. Following developments of ATM (Asynchronous Transfer Mode) technology, more core networks become ATM-based. Therefore, the demand of mobility on wireless networks with ATM backbones is increasing. In recent years, several location management schemes have been proposed for classical wire...

With the availability of location based services, applications that use locations for optimal performance will require efficient location management algorithms, where user locations are kept track with minimal system overhead. Geography based routing in mobile ad hoc networks is one such application that uses location information of nodes in a network to route data packets. Previous work in thi...

Integration of WLAN hotspots into next generation cellular networks requires considerations on location management, resource allocation, handoff algorithms and their sensitivity to mobility related features such as velocity of the mobile and the handoff delay. This article presents architecture for seamless location-aware integration of WLAN hotspots into cellular networks and provides an analy...

An information-theoretic framework is developed for optimal location management in multi-system, fourth generation ( ) wireless networks. The framework envisions that each individual sub-system operates fairly independently, and does not require public knowledge of individual sub-network topologies. To capture the variation in paging and location update costs in this heterogeneous environment, ...

Next Generation Wireless Networks (NGWN) are proposed to achieve the goal of ubiquitous broadband networking by utilizing multiple wireless access subnetworks serving overlapping areas. Location management schemes play a very important role in NGWN since mobile users roam in coverage areas of these subnetworks simultaneously. The performance of location management schemes directly affect the ov...

EEcient abstractions for Location management is a key consideration in wireless networks that support Universal Personal Communications. Location management involves a tracking component that maintains dynamic data on the location of mobile stations through a distributed database, and a search component that prescribes the manner in which the wireless network is to be paged so as to determine t...
