Claim:
1. A method for controlling transmissions of a batteryless device operating in a wireless network, the method comprising: transmitting, by the batteryless device over a wireless communication interface to a controlled device, a control frame including elements for controlling operation of the controlled device, the batteryless device being configured with a number of planned retransmissions of the control frame; sensing, by the batteryless device with a sensor, a change in a physical phenomenon induced by an operation of the controlled device, the operation of the controlled device being based on receiving the transmitted control frame, wherein the sensing of the change in the physical phenomenon is performed by the sensor device included in the batteryless device and different from the wireless communication interface; determining, by the batteryless device and based on the sensing, whether the transmitted control frame was received successfully by the controlled device; and canceling the further planned retransmissions of the control frame when the batteryless device determines the control frame was received successfully.
