A novel metric for Dynamic Channel Assignment in enterprise wireless networks

In enterprise wireless networks where Access Points (APs) are densely deployed, the importance of Dynamic Channel Assignment (DCA) is more emphasized since the network is under severe inter-cell interference. In this paper, we propose Contention Factor (CF) as a metric for DCA in enterprise wireless networks. The metric is designed to minimize the performance degradation by separating collision domains of APs. Simulation results demonstrate that the proposed metric precisely predicts the network performance so that DCA utilizing the proposed metric improves the overall network throughput.
