VoIP applications have grown rapidly and continue to enjoy exponential growth due to largely reduced cost and wider range of advanced services, as compared to traditional telephone network., however, they face many technical challenges. One of major challenges is the provision of quality of service. Presently, VoIP quality is not as good as achieved in traditional telephone networks due to the data loss and delay in IP networks. In this paper, a perceptual quality-driven scheduling scheme is proposed. Simulation experiments results show that it significantly increases the quality of voice traffic transmission over IP network yielding QoS satisfaction both for VoIP users and service providers
