future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

Mobile commerce and location based services (LBS) are some of the fastest growing IT industries in the last five years. Location update of mobile clients is a fundamental capability in mobile commerce and all types of LBS. Higher update frequency leads to higher accuracy, but incurs unacceptably high cost of location management at the location servers. We propose ROADTRACK – a roadnetwork based...

Effective location tracking strategy is essential to improve the utility of radio channels [1]-[6]. Due to the limited battery life and computational capacity in a mobile station (MS), one desirable feature of a location update scheme is its easy implementation in the MS. A movement-based location update scheme [4] is one of the easily implementable approaches. According to this scheme, each MS...

Location management is an important problem in distributed mobile computing. Location management consists of location updates, searches and search-updates. An update occurs when a mobile host changes location. A search occurs when a mobile host needs to be located. A search-update occurs after a successful search. Various strategies can be designed for search, update and search-update. Static l...

Mobility management is a necessity in highly dynamic and large-scale mobile agents network, especially in a multi-region environment in order to control and communicate with agents after launching. Existing mechanisms for locating mobile agents are not efficient as these do not consider the effect of location updates on migration time and produce network overload. A location management protocol...

In mobile wireless networks, efficient location management for tracking and finding the mobile users is a critical issue. The traffic for location update can be excessive, especially at base stations that are near location area (LA) boundaries. In this paper we propose a new location update scheme which can significantly reduce the signaling traffic for location update. It is based on the virtu...
