In this paper a new distributed adaptive admission control algorithm for wireless cellular networks with heterogeneous traffic is proposed. The resources needed for handoff calls are estimated by calculating the probability of visiting particular cells during the call lifetime based on the call duration and residence time statistics. This information is then communicated to the base stations in the S surrounding rings. The amount of reserved resources is updated at handoffs and call termination which involves simple arithmetic operations only. The admission algorithm also maintains the tuning parameters by which hard constraints on handoff dropping probabilities can be met. We have also derived the QoS bounds for homogeneous traffic
