Wireless networks are common in large organisations that can cover multiple floors and buildings. Wireless networks become expensive as they grow and more control and coordination is needed to operate and management them. This thesis describes how CloudMAC, a software defined networking solution (SDN), were implemented in OpenDaylight Hydrogen, a SDN controller. CloudMAC reduces complexity in large wireless local area networks. CloudMAC splits access points (AP) into, a physical (accesses the wireless medium) and a logical (handles the processing of data) part. These two part are then placed in different locations in a wired network. The parts are connected by making tunnels through the network. Some of the communications in wireless networks are time sensitive. Such time sensitive communication is easily disturbed during congestion. To improve CloudMAC, quality of service (QoS) was implemented. QoS was used both in the wired network and in accessing the wireless medium. Evaluations shows how to evaluate queues utilization and performance.
