Recently, wireless networking technologies have been evolving to support wider bandwidth, and longer radio range in denser networks. Therefore, there is a high probability that two or more networks will overlap and result in more co-channel interferences. To mitigate the interference, the centralized network system is a promising solution which is based on the conflicts information provided by the interference detection methods. However, in this paper, we reveal that the existing Passive Interference Detection method (PIE) is not accurate and may cause dramatic throughput decrease in dynamically interfered networks because it is based on a single data rate criterion. Moreover, we propose and implement AMONET, which is a centralized detection method considering the data rate degradation due to interference (DRDI). Our simulation results demonstrate that the proposed scheme can improve aggregate throughput by 2.68x gains in the interfered wireless links over distributed coordination function (DCF), while PIE achieves 1.8x gains over DCF.
