摘要：

Call Admission Control (CAC) protocols play a very important role in the performance of wireless networks. In this paper, we present a call admission control protocol for cellular wireless networks. Our protocol depends on degrading the existing calls by reducing the bandwidth allocated to them in order to admit "important" calls. Our protocol assign priorities for the incoming calls, and in the same time assign priorities to the existing calls, both admitted calls are admitted according to their priorities and the existing calls are degraded according to their priorities. We show simulation results for the relation between network utilization, call blocking probability, and average assigned bandwidth during the life of the call.
