Abstract
A method of coordinating sampling instants of a plurality of mobile ambient sensors, comprising: receiving a definition of a measuring zone; detecting simultaneous presence of two or more mobile ambient sensors in the measuring zone; and assigning sampling instants to each of said two or more sensors, wherein the assigned sampling instants apply until a change in said simultaneous presence is detected.
Claims15
A method of coordinating sampling instants of a plurality of mobile ambient sensors, which method is performed by a controller equipped with or connected to a communication interface with the mobile ambient sensors and comprises:
- receiving a definition of a measuring zone;
- detecting simultaneous presence of two or more mobile ambient sensors of the a plurality of mobile ambient sensors in the measuring zone, wherein the detection of said simultaneous presence is based on a relative positioning procedure among the plurality of mobile ambient sensors, a geolocation procedure performed at one of the plurality of mobile ambient sensors, a report received from a fixedly located radio transceiver in the measuring zone, or one or more measurement reports received by the controller from two or more mobile ambient sensors in the measuring zone;
- assigning sampling instants to each of said two or more mobile ambient sensors, wherein the assigned sampling instants apply until a change in said simultaneous presence is detected;
- operating the two or more mobile ambient sensors based on the assigned sampling instants.
A controller operable to coordinate sampling instants of a plurality of mobile ambient sensors, which method is performed by a controller equipped with or connected to a communication interface with the mobile ambient sensors and the controller comprises:
- a wireless interface configured to:
- receive a definition of a measuring zone;
- and
- detect simultaneous presence of two or more mobile ambient sensors in the measuring zone,
- wherein the detection of said simultaneous presence is based on a relative positioning procedure among the two or more mobile ambient sensors, a geolocation procedure performed at one of the two or more mobile ambient sensors, a report received from a fixedly located radio transceiver in the measuring zone, or one or more measurement reports received by the controller from two or more mobile ambient sensors in the measuring zone,
- processing circuitry configured to:
- assign sampling instants to each of said two or more mobile ambient sensors wherein the assigned sampling instants apply until a change in said simultaneous presence is detected;
- and
- operate the two or more mobile ambient sensors based on the assigned sampling instants.
