Abstract—The scarcity of non-overlapping channels is always an important issue especially in case where access points (APs) are very dense. This paper presents a distributed dynamic channel assignment (DCA) algorithm to improve network throughput and decrease the computation complexity by maximizing the sum of weighted signal to interference plus noise ratio (SINR). The proposed scheme allows using partially overlapping channels instead of non-overlapping channels. Simulation results show the effectiveness of the proposed algorithms and compare the performance with the state-of-the-art DCA
