Abstract
In a wireless local area network, an access point failing to adhere to proper power management protocol is detected by analyzing a beacon frame sent by the access point to determine if a traffic information map (TIM) in the beacon frame is zero. A frame sent by a station is analyzed to determine if the station is in a power save mode. A data frame sent by the access point is analyzed to determine if the data frame is destined for the station. An improper power management protocol condition of the access point is determined based on the foregoing analysis.
