CCOD’s performance was evaluated in two topologies: static and dynamic. In the first one, the number of the stations connected to the network didn’t change over time. In the dynamic topology, the number of the stations was steadily increasing from 5 up to the goal number.
Two first graphs show how the mean network throughput changed with varying number of stations. The third one shows the momentarily throughput in the dynamic topology, in which the simulation starts with 5 stations and ends with 50.
Take a note on how quickly the performance of the stock 802.11ax CW control mechanism detoriates with the increasing number of stations. With 50 devices competing for the medium, the CCOD noted an improvement in throughput of over 40%
