A Stop-or-Move Mobility model for PCS networks and its location-tracking strategies

A Traveling Salesman Mobility Model and Its Location Tracking in PCS Networks

This paper considers the location tracking problem in PCS networks. How a solution to this problem peflorms in fact highly depends on the mobility patterns of users [14]. In this paper; we propose a new Traveling Salesman Mobility (TSM) model, in hope of catching the mobility patterns of a large group of users. The TSM model is characterized by features of “stop-or-move ”, “infrequent transitio...

Predictive Distance-Based Mobility Management for PCS Networks

This paper presents a mobile tracking scheme that exploits the predictability of user mobility patterns in wireless PCS networks. Instead of the constant velocity fluid-flow or the random-walk mobility model, a more realistic Gauss-Markov model is introduced, where a mobile’s velocity is correlated in time to a various degree. Based on the Gauss-Markov model, a mobile’s future location is predi...

Reducing location update and paging costs in a PCS network

Mobility Tracking operations in a personal communication service (PCS) system are signaling consuming. Several strategies have been proposed in the literature to reduce both, the location update (LU) and the paging (PG) costs. In this paper, we propose a location-tracking algorithm called three-location area (TrLA), combined with selective paging. In the TrLA, the mobile terminal (MT) allocates...

Location Tracking in PCS Networks Using Enhanced Caching

In personal communication service (PCS) networks, the user location tracking strategy plays a critical role in ensuring successful mobile communication in any place at any time. The IS-41 scheme in North America and the MAP of the GSM system in Europe are two current standard location tracking schemes. To reduce communication cost for the two basic schemes, several location tracking strategies,...
