Performance Modeling of Cellular Mobile Systems: A Review of Recent Advances

In this paper, we review some of the earlier studies on performance modeling of cellular mobile systems and their improvements proposed in some recent studies. These studies deal with a number of cellular mobile traffic models for fixed channel allocation and dynamic channel allocation, considering the cases, where user population is either infinite or finite. Further, the modeling of handoff process based on various traffic profile has also been investigated. The proposed traffic models were used for mobility modeling and performance analysis in terms of some Quality of Service (QoS) parameters. We also comment on the -future scopes of performance analysis in the context of Green Information and Communication Technologies, which may lead to energy-efficient and environment friendly future cellular mobile systems.
