This paper proposes an adaptive quality-of-service (QoS) control to increase the robustness of MPEG-4 video communication over wireless channels. More specifically, the proposed adaptive QoS control consists of optimal mode selection and delay-constrained hybrid automatic repeat request (ARQ). The optimal mode selection is employed to provide QoS support on the compression layer while delay-constrained hybrid ARQ is used to provide QoS support on the link layer. Simulation results show that the proposed adaptive QoS control achieves satisfactory quality for MPEG-4 video under dynamically changing wireless channel conditions and utilizes network resources efficiently.
