Abstract In this paper, a practicable user traffic satisfaction evaluation model of the VoIP traffic and the real-time video traffic is proposed. This method calculates the user’s traffic quality of experience according to the packet loss rate and the packet loss pattern measured in MAC layer. Using the proposed traffic satisfaction evaluation criterion, a satisfaction based packet scheduling and resource allocation algorithm is proposed. The simulation results show that, the proposed algorithm can provide better traffic satisfaction to users while keeping a high system throughput.
