Multi-Channel Wi-Fi experiments are quickly becoming more common and relevant as Wi-Fi deployments have become extremely popular and dense in recent years. There are many simulation tools available for Wi-Fi simulation, but few are widely used, and some are not designed specifically with wireless in mind. In this paper, the NS3 environment is recognized as a promising tool for which for this type of work. Limitations in certain simulation scenarios are identified with respect to the existing NS3 wireless modules. A novel NS3 simulation module is proposed, which provides support for multi-channel Wi-Fi AP selection, so that user devices may scan several non-interfering channels and select the best AP according to IEEE 802.11 criteria. The simulation module presented is carefully studied, evaluated and validated, and is ready for use.
