Abstract

In wireless cellular network with heterogeneous services, providing guaranteed Quality of Service (QoS) poses a great challenge due to the scarce radio bandwidth. Often researchers in this field have tried to reduce the handoff call dropping probabilities (HCDP) in a cell at the sacrifice of increasing the new call blocking probabilities (NCBP). In this paper we propose a call admission control (CAC) scheme for WiMAX networks to achieve a fair trade-off between NCBP and HCDP. Numerical results showed that the proposed CAC scheme shows improvement in NCBP without affecting HCDP.

Keywords: WiMAX QoS Markov chain CAC Trade off
