ABSTRACT:
Provides: methods for transmission of signals between a sensor and a controller in a wireless sensor network; methods for operating the controller in the wireless sensor network; and methods for transmitting a sensor signal in the wireless sensor network from the sensor to the controller. A wireless sensor network includes a controller connected with multiple antennas for sending out a beacon signal at different instants into different directions and for receiving a sensor signal. Furthermore, the wireless sensor network comprises a sensor having a receiver connected with a sensor antenna for receiving the beacon signal, a transmitter connected with the sensor antenna for sending out the sensor signal, and a control unit which takes care that the sensor signal is transmitted after the beacon signal has been received.
