Performance Evaluation of an Enhanced Distance-Based Registration Scheme Using the Normal Distribution Approximation

Abstract

SUMMARYHaving an efficient location management scheme for mobile stations (MSs) is very important for optimizing the performance of mobile cellular systems. In this study, a distance-based registration (DBR) scheme and an enhanced DBR scheme are examined.According to computer simulations on the DBR scheme, we show that most MSs tend to distribute around the center of the location area. This centralizing property of the MS in the DBR scheme enables us to approximate the distribution of the MS in the location area to a normal distribution. We analyze the performance of the DBR scheme according to the above approximation and our mobility model. We also propose a distance-based implicit registration (DIR) scheme in order to improve the performance of the DBR scheme. We evaluate the performance of the proposed scheme using the normal distribution approximation to compare to the performance of the DBR scheme. The numerical results show that the DIR scheme not only outperforms the DBR scheme in all the cases, but also outperforms the zone-based registration (ZBR) scheme in most cases.

Modeling and optimization of zone-based registration considering cell-by-cell location area for mobile communication networks

“…There has been considerable research into efficient mobility management schemes [1][2][3][4][5][6][7][8][9]. Among them, zone-based registration (ZBR) is the most popular location registration scheme and is the one that has been adopted by most mobile communication networks.…”
