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 are becoming ATM-based. Therefore research into location management schemes for wireless networks with ATM cores is attracting more attention. In recent years several location management schemes ha...

Location-Dependent Information Services is an emerging class of application that allows new types of queries such as location-dependent queries and continuous queries. In these systems, data caching plays an important role in data management due to its ability to improve system performance and availability in case of disconnection. In mobile environment, cache management requires more than trad...

Location management is a key component of cellular networks. From a privacy perspective, however, it is also a major weakness: location management empowers the network operator to track users. In today’s public and scientific discussion, the centralized storage of location data is mostly taken as a fact, and users are expected to trust the network operator. ANOTEL presents a novel, clean-slate ...

Location management being a major part of cellular network provides mobility to mobile subscribers. The current location information is required to route the call correctly to the recipient irrespective of its current location. The current HLR/VLR architecture for location management in standards like IS-41 & GSM suffers from call setup delay due to network congestion and also prone to failure ...

Effective location management is critical for future personal communication service (PCS) networks, which envision smaller cells comprising a vast number of mobile terminals. In this paper we present a dynamic location management scheme with personalized location areas. The proposed technology takes into account the mobility patterns of the individual users in the system. The continuous time Ma...

We propose a diversity-guided group search optimizer-based approach for solving the location management problem in mobile computing. The location management problem, which is to find the optimal network configurations of management under the mobile computing environment, is considered here as an optimization problem. The proposed diversity-guided group search optimizer algorithm is realized wit...

A mobile ad hoc network (MANET) is a kind of wireless ad hoc network. It is a self-configuring network of mobile routers connected by wireless links. Since MANETs do not have a fixed infrastructure, it is a challenge to design a location management scheme that is both scalable and cost-efficient. In this paper, we propose a cooperative location management scheme, called CooLMS, for MANETs. CooL...

Recently, a new family of protocols has been introduced for large scale ad hoc networks that make use of the approximate location of nodes in the network for geography based routing. Location management plays an important role in such protocols, and previous work in this area has shown that the asymptotic overhead of location management is heavily dependant on the service primitives (location r...

In ad-hoc networks, geographical routing protocols take advantage of location information so that stateless and efficient routing is feasible. However, such routing protocols are heavily dependent on the existence of scalable location management services. In this paper, we present a novel scheme to perform scalable location management. With any location management schemes, a specific node, A, i...

Location management schemes continue to be a topic of major research. Especially with the upcoming 3G, 4G and wireless LAN technologies, which will bring better services to the mobile users, it is anticipated that the mobile user population would continue to increase. Location management schemes comprise of location update and paging procedures. Efforts to introduce an efficient location update...
