Mobile agents are processes that can be dispatched from source computer and be transported to remote servers for execution, have been widely argued to be an important enabling technology for future systems. Location management is a necessity for locating mobile agents in a network of mobile agent hosts for controlling, monitoring and communication during processing and it still represents an op...

In this paper, we propose a stochastic model to compute the optimal update boundary for the distance-based location update algorithm. The proposed model is flexible and captures some of the real characteristics in the wireless cellular environment. The model can adapt to arbitrary cell topologies in which the number of neighboring base stations at different locations may vary. The cell residenc...

In mobile ad hoc networks, nodes are dynamically changing their locations. The QoS information used for routing by traditional QoS routing protocols becomes obsolete due to node mobility. To overcome this problem, a predictive QoS routing scheme is needed. In this paper, we present a location-delay prediction scheme, based on a location-resource update protocol, which assists a QoS routing prot...

Mobility management plays a central role in providing ubiquitous communications services in future wireless mobile networks. In mobility management, there are two key operations, location update and paging, commonly used in tracking mobile users on the move. Location update is to inform the network about a mobile user’s current location, while paging is used for the network to locate a mobile u...

Personal Communication Systems (PCS) maintain a Location Management mechanism for tracking the location of their mobile users. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. This work presents a new mobility management scheme that integrates the location area approach with the location ...

In this work, we develop a novel mathematical model to analyze di erent location update protocols for mobile cellular network. Our model can capture many important features of user movements, such as geographically dependent movement, directional movement and nonexponential distribution of cell dwell times. We propose to use the transient method to predict the location of a mobile user. This me...

An important issue of wireless sensor networks is object tracking, where the key steps include event detection, target classification, location estimation and location management. The main theme of this paper is location management. Because imprecision is an inherent property in object-tracking sensor networks, this paper focuses on the scenarios where users can tolerate a certain degree of imp...

Tracking is an enabling technology for many location based services. Given that the location of a moving object changes continuously but the database cannot be updated continuously, the research issue is how to accurately maintain the current location of a large number of moving objects while minimizing the number of updates. The traditional approach used in existing commercial transportation s...

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. This paper introduces a new schema in management of mobile nodes location in mobile ad hoc networks. Fuzzy logic optimization is applied to a better management of location upd...
