The channel assignment scheme based on system interference evaluation model for WLAN

In this paper, we proposed a WLAN system interference evaluation model based on received signal power and working channels which reflects the system interference in the current channel configuration. Based on this model, we proposed a simple and effective channel assignment scheme in which a set of channels with minimum system interference values were selected as the APs working channels. Simulation results show that a set of channel selected using the proposed schema is appropriate which effectively avoids the adjacent APs using the same channel and reduces the mutual interference between APs.
