Abstract(in English) Automated interference detection is required for operation and management services in wireless networks as 802.11 WLANs since co-channel interference from other wireless transmitters occurs irregularly. We propose a new approach for detecting the presence of interference on 802.11 links. Our solution focuses on the Access Point-side monitoring approach without station-side additional function and sniffer devices. Our approach uses the phenomenon of response delay increasing by interference in the CSMA/CA protocol to detect the generation of interference by monitoring response delay from all stations to AP initiated packets. The proposed method consists of a continuous monitoring step and a periodical diagnosis step to measure network statistics by ACK response delay between an AP and stations. The numerous results of simulation show that the proposed approach has a good accuracy and low misdetection ratio for diagnosing the interference existence and location in 802.11 WLANs.
