Performance analysis of 2-location distance-based registration in mobile communication networks

In this study, 2-location distance-based registration (2DBR) is proposed to improve the performance of traditional distancebased registration. In distance-based registration, when a mobile station (MS) enters a new cell, the MS calculates the distance from the last registered cell and registers its location if the calculated distance reaches a prescribed distance threshold D. In 2DBR, an MS stores not only the last registered location area (LA) but also the second-to-last LA, and then no registration is performed when the MS crosses the two stored LAs. The 2DBR may increase paging cost but it may decrease registration cost. Simulation results show that our proposed 2DBR outperforms current distancebased registration in most cases.
