Packet scheduling algorithm is the key technology to guarantee Quality of Service (QoS ) and balance the fairness between users in broadband Wireless Metropolitan Area Network (WMAN ). Based on the research of Proportional Fairness (PF ) algorithm and Modified Largest Weighted Delay First (M-LWDF ) algorithm, a new packet scheduling algorithm for real-time services in broadband WMAN, called Enhanced M-LWDF (EM-LWDF ), was proposed. The algorithm phases in new information to measure the load of service queues and updates the state parameters in real-time way, which remarkably improves system performance.Simulation results show that comparing with M-LWDF algorithm, the proposed algorithm is advantageous in performances of queuing delay and fairness while guaranteeing system throughput.
