Wi-Fi interface is known to be a primary energy consumer in mobile devices, and Idle Listening (IL) is the dominant source of energy consumption in Wi-Fi. Most existing protocols, such as the 802.11 Power-Saving Modes (PSMs), attempt to reduce the time spent in IL by sleep scheduling. However, through an extensive analysis of real-world traffic, the authors found more than 60% of energy is consumed in IL, even with PSM enabled. To remedy this problem, they propose "Idle listening and reducing energy consumption in wireless networks" that reduces the power consumption in IL, given that the time spent in IL has already been optimized by sleep scheduling.
