This paper introduces control systems, which regulate tranceivers' packet sizes for prevailing network conditions to achieve maximum throughput and minimum delay for real-time traffic in Wireless Local Area Networks (WLANs). Delay and throughput are very much dependent on the packet size and the connection density. Therefore, the selected input parameters for the controllers are one-way delay and change of delay. The models were valitated by simulating User Datagram Protocol (UDP) traffic in OMNeT++ network simulator. The results demonstrate that the developed controllers are able to set packet sizes to the prevailing optimum level and increase overall throughput of the network.
