Abstract
We present queueing analysis for two connection admission control (CAC) schemes for OFDM wireless networks. The first one is a threshold-based CAC scheme in which admissibility for a new connection is determined based on a certain threshold and the number of ongoing connections. The second scheme uses the information on queue status to determine the probability to accept an incoming call. The connection-level and the packet-level performance measures for both CAC schemes are obtained from the queueing analytical models. Typical numerical results based on the proposed model are presented which provide interesting insights on the behavior of these two different CAC schemes. Also, simulation results are presented to validate the analytical results
