Abstract	Adaptive multimedia is promising in wireless/mobile networks since it mitigates the fluctuation of resources caused by the mobility in wireless/mobile networks. However, its bandwidth adaptation causes the bandwidth degradation. In order to fully characterize the bandwidth degradation and to provide better QoS to service users, we propose two new QoS parameters for adaptive multimedia: The Degradation Ratio (DR) and the Degradation Degree (DD), which characterize both the frequency of degradation and the degree of degradation. A measurement-based Call Admission Control framework and a K-Level Bandwidth Adaptation Algorithm (KL-BAA) are also proposed to satisfy the proposed QoS parameters' requirements, and to utilize the resource efficiently. Moreover, the measurement-based formulas for DR and DD are provided using the time averaging method. Simulation results show that QoS requirements are satisfied, and KL-BAA outperforms the Two-Level Bandwidth Adaptation Algorithm. Simulation results are also compared with those from the non-adaptive multimedia services and reveal that the adaptive multimedia framework outperforms the non-adaptive multimedia services.
