Abstract:
A method of selecting and controlling devices based on wireless communication technology. The wireless controller sends a probe message to one or more devices; each device receives the probe message, obtains information in respect of its relative position with respect to the wireless controller, determines a response time to respond according to a first predefined rule, based on its relative position information: detects response signals from other devices before expiration of the response time; decides whether to send or not to send its response signal according to a second predefined rule and the detecting procedure of response signals from other devices; the wireless controller receives response signals sent by the devices after the comparison of the relative position information of each device with respect to the wireless controller, and selects the target devices from the devices. Embodiments of the present invention reduce the complexity, delay and energy consumption of the selection for wireless devices, and are especially applicable for wireless lighting systems.
