Abstract
An access point that performs collaborative detection of an electronic device is described. During operation, the access point may receive a request from a second access point using wired or wireless communication, where the request specifies a communication channel. In response to this request, the access point may perform a wireless scan of the specified communication channel. Moreover, the access point may provide, using wired or wireless communication, a trigger message to the second access point with an instruction for the second access point to provide fake traffic to the electronic device. Then, the access point may receive, using wireless communication, a response from the electronic device to the fake traffic. Next, the access point may provide, using wired or wireless communication, a report to the second access point with information specifying at least a communication performance metric of the electronic device.
