Performance Analysis of the Distributed Location Management Scheme in Large Mobile Networks
Dong-Chun Lee, Hongjin Kim, Jong Chan Lee, Yi‐Bing Lin · Journal of Information Processing Systems · 2005
In this paper we propose a distributed location management scheme to reduce the bottleneck problem of HLR in Large Mobile Networks (LMN). Using analytical modeling and numerical simulation, we show that replicating location information is both appropriate and efficient for small mobile networks. Then, we extend the scheme in a hierarchical environment to reduce the overhead traffic and scale to LMN. In numerical results, we show the superiority of our scheme compared to the current IS-95 standard scheme in IMT-2000 networks.
