TQ/PSO - A New Scheduler to Optimize the Time Frame with PSO in WiMAX Networks

The technological advances of recent years caused a growth in the base of users sharing communication networks, especially with multimedia services such as IPTV, video conferencing and VoIP. These services require more resources and generate a large demand on the infrastructure of the network. Thus, the communication networks for wireless broadband, based on the IEEE 802.16 standard, known as WiMAX, meet the various demands of end users, such as the need for data access at all times and anywhere connectivity and bandwidth large effective. The guarantee of quality of services is a major factor for the performance of communication networks, for this, the scheduling mechanisms, call admission control and traffic policing, should be present. However, the IEEE 802.16 standard only specifies the mechanisms of how these policies should be implemented, but does not define how to implement them. Thus, this article aims to present a new scheduler for traffic uplink, with guaranteed provision of quality services, using the meta-heuristic particle swarm optimization, to calculate the duration of time frame, making possible to find an ideal value, which will provide a better allocation of network users.
