We propose a new connection admission control algorithm called DAC for real-time services in packet-switched OFDM wireless cellular networks. The main idea of DAC is to use maximum acceptance ratio for real-time services according to the desired packet-level and call-level QoS requirements. The control mechanism is periodical. At the beginning of the control period, the admission controller gathers the loading information from its own and neighboring cells. Then, according to the information, the maximum acceptance ratio is calculated by using a Markovian queueing model and time-dependent distribution of the number of connections. Finally the admission controller uses the computed ratio to admit connection requests in this control period. Extensive simulation results show that our algorithm satisfies packet-level and call-level QoS requirements for real-time services while maintaining high bandwidth utilization.
