Abstract
A sensor for use in a wireless sensor network of devices, comprising: sensing means operable to detect values of a parameter; control means operable to determine a suitable sleep pattern of the sensor taking into account the detected values and a transmitter operable to transmit an indication of the suitable sleep pattern to a further device in the wireless sensor network.
Claims15
A sensor for use in a wireless sensor network of devices, comprising:
- sensing means operable to detect values of a parameter;
- control means operable to determine a suitable sleep pattern of the sensor taking into account the detected values and
- a transmitter operable to transmit an indication of the suitable sleep pattern to a further device in the wireless sensor network.
A wireless sensor network of devices including a sensor and a coordinator:
- the sensor comprising sensing means operable to detect values of a parameter;
- transmission and reception means;
- and sensor control means operable to control the sleep pattern of the sensor;
- and
- the coordinator comprising transmission and reception means;
- wherein
- the sensor is operable to determine its own suitable sensor sleep pattern taking into account the detected parameter values, and to influence coordinator operation by transmission of an indication of its suitable sleep pattern.
A coordinator in a wireless sensor network of devices including sensors and the coordinator, wherein the coordinator comprises
- transmission and reception means for communication with the sensors;
- and
- coordinator control means operable to influence functioning of the coordinator in response to an indication of a suitable sleep pattern transmitted by a particular one of the sensors.
