Abstract
In a method for operating a wireless sensor network (1) with a plurality of sensor nodes (2-4), which are suitably set up to transmit data by nondirectional radio transmission, a selected set containing at least one sensor node (2) can be selectively moved from a first operating state into a second operating state by a spatially delimited first operating state control signal (17), with the sensor node (2-4) in the first operating state not being able to receive control data by nondirectional radio transmission and in the second operating state, being able to receive and process control data by nondirectional radio transmission. Furthermore, a sensor node can be suitably configured to implement the method.

- 23. A method for operating a wireless sensor network comprising a plurality of sensor nodes, which are suitably configured to transfer data by means of nondirectional radio transmission, with it being possible for a selected set containing at least one sensor node to be moved selectively from a first operating state into a second operating state by means of a spatially delimited first operating state control signal, with the sensor nodes in the first operating state not being able to receive or at least process control data by means of nondirectional radio transmission and being able to receive and process control data in the second operating state by means of nondirectional radio transmission and with it being possible for the sensor nodes of the sensor network to be moved from a third operating state into the first operating state by means of a second operating state control signal, with the sensor nodes in the third operating state not being able to receive or at least process the first operating state control signal and in the first operating state being able to receive and process the first operating state control signal.

39. A sensor node which is provided with at least one sensor for scanning data, a transmitter-receiver for transmitting data by means of nondirectional radio transmission and a microprocessor-based control facility for controlling the sensor node, in which the control facility is suitably set up to
selectively move a selected set containing at least one sensor node from a first operating state into a second operating state by means of a spatially delimited first operating state control signal, wherein the sensor nodes in the first operating state are not able to receive or at least process control data by means of nondirectional radio transmission and are able to receive and process control data in the second operating state by means of nondirectional radio transmission and to move sensor nodes of the sensor network from a third operating state into the first operating state by means of a second operating state control signal, wherein the sensor nodes in the third operating state are not able to receive or at least process the first operating state control signal and in the first operating state being able to receive and process the first operating state control signal.

40. A method for operating a wireless sensor network comprising a plurality of sensor nodes, which are suitably configured to transfer data by means of nondirectional radio transmission, the method comprising:
-
selectively moving a selected set containing at least one sensor node from a first operating state into a second operating state by means of a spatially delimited first operating state control signal, wherein the sensor nodes in the first operating state are not able to receive or at least process control data by means of nondirectional radio transmission and are able to receive and process control data in the second operating state by means of nondirectional radio transmission and moving sensor nodes of the sensor network from a third operating state into the first operating state by means of a second operating state control signal, wherein the sensor nodes in the third operating state are not able to receive or at least process the first operating state control signal and in the first operating state being able to receive and process the first operating state control signal. - View Dependent Claims (41, 42)
