in this paper, a location allocation (la) problem in construction and demolition (c&d;) waste management (wm) is studied. a bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control c&d; waste and the after tre...

This paper presents two mobile location management algorithms for ATM (asynchronous transfer mode) networks based on the PNNI (private network-to-network interface) standard. The first solution is called the mobile PNNI scheme because it builds on the PNNI routing protocol. It uses limitedscope (characterized by a parameter S) reachability updates, forwarding pointers, and a route optimization ...

One of main issues in mobile wireless networks is how to deal with moving terminals. As the movement implies a change of access point, the wireless network must be able to determine the location of moving terminals in order to set-up a connection and route incoming messages. Location management is for tracking and locating the mobile terminal. In this paper we propose a novel location managemen...

The ever-increasing demand of mobile system is posing a great challenge for efficient call delivery due to tremendous surge in numbers of mobile subscribers. In order to scale well with increased users, the efforts are underway to develop the new location management techniques as well as to optimize the existing ones so as to keep up-to-date information about current location of mobile phones w...

The challenge of supporting rapidly growing numbers of mobile subscribers, while constrained by limited radio spectrum, is being met through increasingly smaller radio cells. This, however, results in increased signalling for location management procedures, which reduces the bandwidth available for user traffic. Location areas in current systems, such as GSM, consist of static and arbitrarily-d...

This paper presents a framework for modeling and evaluating the performance of location management schemes for a Personal Communication Services (PCS) network. The models take into account complex human behaviors, and are based on actual measurements of these behaviors. Real measurements are a crucial factor in achieving realistic performance evaluations. We have developed a powerful and highly...

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...

Digital rights management allows information owners to control the use and dissemination of electronic documents via a machine-readable licence. This paper describes the design and implementation of a system for creating and enforcing licences containing location constraints that can be used to restrict access to sensitive documents to a defined area. Documents can be loaded onto a portable dev...

t This paper gives a comparative description of two scenarios for location management in a mobile telecommunications system. The first scenario uses fixed location and paging areas. Mobiles perform a location update as they enter a new location area. The second scenario uses a time-out based location updating scheme. Mobiles start their timer as they leave the paging area they are currently reg...

With the rapid increase in international roaming and highly growing number of cellular subscribers it is important to locate the subscriber both efficiently and accurately not only to reduce the cost but also to decrease the load on MSC and decrease the paging delay. The procedure used by the service provider for both collecting and analyzing the information regarding the subscribers’ location ...
