An architecture for mobility management in mobile computing networks

Abstract

In this paper, we present an efficient architecture for mobility management in mobile computing networks. The proposed architecture reduces the registration update cost and organize the physical location information databases in the lowest level into clusters, called logical groups, which are then represented by logical nodes in the next layer up. These logical nodes are regrouped into clusters and treated as single nodes in the next level up for all successive levels until all mobility agents are included in a tree-type logical hierarchy architecture. The performance evaluation of the proposed architecture is achieved via modeling analysis. The corresponding results demonstrate the proposed architecture can efficiently reduce the number of databases and average total registration cost. © Springer-Verlag Berlin Heidelberg 2004.
