Abstract

Various interfaces such as application programming interfaces (APIs) are employed to allow developers to construct applications that use multiple shared sensors. In one instance, a coordinator can be utilized to facilitate coordination of sensor data contributors and applications desirous of utilizing such data. Standardized interfaces can be employed to aid interaction between all entities including contributors, applications and a coordinator, amongst others.

Claims

1. A system to facilitate sensor interaction, comprising:

a coordinator component that acquires and maintains sensor data contributed by a plurality of entities; and

an interface component that facilitates interaction between the coordinator and an application that utilizes the sensor data.

2. The system of claim 1, further comprising a sensor index component to facilitate discovery of sensors of interest.

3. The system of claim 1, further comprising a data component to facilitate identification of desired sensor data for acquisition.

4. The system of claim 3, sensors from which data is acquired are identified by location, time, or sensor id.

5. The system of claim 3, data processing is specified for execution on the data prior to acquisition.

6. The system of claim 5, the processing is data aggregation including sum, average, maximum, and/or minimum.

7. The system of claim 1, further comprising a component to specify data sampling and/or report rates.

8. The system of claim 1, the interface component is a standardized interface to the coordinator component.

9. A method of communicating between a sensor contributor and a coordinator of sensed data, comprising:

issuing a request, by a contributor, to register a sensor;

receiving the request, by a coordinator of sensed data; and

registering the sensor with the coordinator.

10. The method of claim 9, further comprising:

issuing a request, by the contributor, to remove the sensor;

receiving the request by the coordinator; and

removing the sensor registration.

11. The method of claim 9, further comprising

issuing a request, by the contributor, to update sensor characteristics;

receiving the request by the coordinator; and

updating sensor characteristics.

12. The method of claim 11, comprising issuing a request to update a sensor location.

13. The method of claim 9, further comprising:

issuing a request, by the contributor, for sensors registered by an identified contributor;

receiving the request by the coordinator; and

returning a list of all sensors registered by the identified contributor.

14. The method of claim 9, further comprising:

issuing a request, by the contributor, for sensing tasks;

receiving the request by the coordinator; and

returning the sensing tasks.

15. The method of claim 9, issuing a request by a gateway.

16. A method of interaction between a gateway and a sensor, comprising:

receiving, by a gateway, a request issued from a sensor to register the sensor; and

registering the sensor with the gateway.

17. The method of claim 16, further comprising receiving data from the sensor.

18. The method of claim 17, receiving binary data, scalar data or vector data.

19. The method of claim 16, further comprising:

receiving, by the gateway, a request issued from the sensor to updated the sensor; and

updating characteristics of the sensor in accordance with the request.

20. The method of claim 16, further comprising:

receiving, by the gateway, a request issued from the sensor to remove the sensor; and

removing registration of the sensor.
