Abstract (en)
[origin: WO2009115448A1] The invention relates to a method for operating a wireless sensor network (1) having a plurality of sensor nodes (2-4) which are suitably set up for data transmission by means of non-directional radio transmission, in which a selection set containing at least one sensor node (2) can be selectively changed from a first operating state to a second operating state by means of a spatially delimited first operating state control signal (17), wherein the sensor nodes (2-4) cannot receive or at least cannot process control data by means of non-directional radio transmission in the first operating state and can receive and process control data by means of non-directional radio transmission in the second operating state. The invention also relates to a sensor node which is suitably set up to carry out the method.
