The rapid growth in the demand for wireless multimedia services makes the provision of quality of service (QoS) an important issue. It is more important in an indoor environment. One of the key requirements of QoS is to reduce the dropping probability of handoff calls. It can be reduced by a proper call admission control (CAC) algorithm. In this paper, we propose a call admission control scheme that is adequate to an indoor environment to resolve the requirement of the dropping probability. Simulation experiments are used to evaluate the performance of the proposed scheme
