Method for controlling transmissions from a resource-restricted device, and batteryless device

摘要

The present invention relates to a method for controlling transmissions of a batteryless device (1) operating in a wireless network, the method comprising the following steps: the batteryless device (1) transmitting a frame including elements for controlling operation of a remote device (2a), or controlled device, the batteryless device being configured with a predetermined number of planned retransmissions of the control frame, the batteryless device sensing a change in the physical phenomenon induced by operation of the controlled device (2a), the batteryless device determining, based on the sensing step, the success or failure of the frame transmission, in case the transmission has succeeded, the batteryless device omitting further retransmissions of the control frame. The present invention also relates to a batteryless device carrying out such method.

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.
