The sharing of communication networks, especially with multimedia services such as IPTV, video conferencing and VoIP has increased in recent years. These services require more resources and generate a great demand on the network infrastructure, requiring the guarantee quality of services. For this, scheduling mechanisms, call admission control and traffic policing should be present to guarantee quality of service. The networks of communication for wireless broadband, based on the IEEE 802.16 standard, called WiMAX are used in this work, because this standard only specify the mechanisms of how these policies should be implemented. Based on these factors, a new architecture was developed in order guarantee the quality of service, using the meta-heuristic Particle Swarm Optimization for fixed WiMAX networks, presenting a method for calculating the duration of the time frame, which allows a control of queues in the scheduler in order to uplink traffic from the base station.
