to real time flows such as video and VoIP in downlink system. By taking the arrival rates of packets to queues into account‚ the proposed mechanism included in previous scheduling algorithms‚ can increase remarkably the bitrate for multimedia services. Simulation results show that the proposed modified algorithms can achieve a throughput gain for real time services specially for video traffic. Performance evaluation is conducted in terms of system throughput and packet loss ratio (PLR). Index Terms—Wireless
