Call admission control using grouping and differentiated handoff region for next generation wireless networks

Abstract

We propose a novel call admission control scheme which improves the handoff drop and the new call block probabilities of high priority services, minimizing the negative impact on low priority services, in multi-service cellular networks. The proposed scheme is a mix of the grouping and the differentiated handoff region scheme. The simulation results revealed that our hybrid scheme improved the drop and the block probabilities of the high priority services compared with the conventional reconfiguration scheme. © Springer-Verlag Berlin Heidelberg 2005.
