Abstract :
In this paper, we present a bandwidth degradation QoS scheme for adaptive multimedia services in next generation wireless/mobile networks, and introduce it in mobile networks to improve the performance of channel allocation. The proposed schemes are the generic call admission control (CAC) algorithm and the admission policy to support multiple rates, multiple class traffic of next generation mobile network. Based on diverse QoS parameters be included in connection request, a two-stage bandwidth degradation QoS CAC algorithm is presented to satisfy the diverse QoS requirement and utilize the system resource efficiently. The simulation results show that the performance of our scheme is preferable to that of existing schemes.
