1. A method comprising:
computing, by a supervisory device for a wireless network, a compressive sensing schedule for a plurality of sensors in the wireless network;
sending, by the supervisory device, target wake time (TWT) messages to a subset of the plurality of sensors according to the computed compressive sensing schedule;
receiving, at the supervisory device and in response to the TWT messages, sensor readings from the subset of the plurality of sensors; and
performing, by the supervisory device, compressive sensing by using the sensor readings received from the subset of the plurality of sensors to reconstruct one or more sensor readings of one or more sensors outside of the subset of the plurality of sensors.
