Modeling and Analysis of Distance-based Registration in Metropolitan Area

摘要

In this paper, we develop a 4-directional mobility model applicable in the metropolitan area to calculate the number of registrations per mobile station (MS) for the zone-based (ZBR) and distance-based (DBR) registration schemes. The analytical results are presented with the assumptions of the MS's uniform distribution in the location area (LA). The simulation studies are also performed to verify the analytical results. The numerical results show that, if the MS's moving distance between turning points is smaller than the distance between incoming calls or LA's radius, the DBR always outperforms the ZBR.
