Performance analysis and optimization of an improved dynamic movement-based location update scheme in mobile cellular networks

Abstract

In this study, we propose an improved version of the dynamic movement-based location update scheme that stores all cells visited by the MS, and their neighboring cells, to reduce the location update cost of the dynamic movement-based location update scheme. We show that a significant reduction in the location update cost is achieved in our scheme. We also show that our scheme has optimal total cost when the threshold is rather small. Additionally, the MS requires a minimal amount of memory to successfully implement our scheme. © Springer-Verlag Berlin Heidelberg 2005.
