Method and apparatus for managing sensor information
In accordance with an example embodiment of the present invention, there is provided an apparatus, comprising a receiver configured to receive sensor data, a transmitter configured to cause the sensor data, or data derived at least in part from the sensor data, to be transmitted, wherein the transmitter is further configured to transmit a metadata request to a first node. In some embodiments, the apparatus is a sensor node for inclusion in a sensor network, the sensor node capable of measuring at least one physical property to produce the sensor data.
1. A sensor apparatus, comprising:
a receiver configured to receive sensor data and, using IPv6 addressing, from a correspondent node, a request to subscribe to information of the sensor apparatus; and
a transmitter configured to cause the sensor data, or data derived at least in part from the sensor data, to be transmitted to the correspondent node,
wherein the transmitter is further configured to transmit a metadata request, distinct from the sensor data, to a first node distinct from the correspondent node and distinct from the sensor apparatus, wherein the metadata request comprises a request that the first node add metadata to the sensor data transmitted from the sensor apparatus and wherein the metadata request does not comprise the requested metadata.
2. The sensor apparatus according to claim 1 , wherein the sensor apparatus comprises at least one sensor element configured to produce the sensor data by physical measurement and to provide it to the receiver internally in the sensor apparatus.
3. The sensor apparatus according to claim 1 , wherein the metadata request comprises a request that metadata be transmitted to the sensor apparatus.
4. The sensor apparatus according to claim 3 , wherein the sensor apparatus is configured to derive contextual sensor data from the sensor data and the metadata, and to cause the contextual sensor data to be transmitted to a second node.
5. The sensor apparatus according to claim 1 , wherein the metadata request comprises a request that metadata be transmitted to a second node.
6. The sensor apparatus according to claim 1 , wherein the metadata request comprises an indicator specifying what kind of metadata the metadata request relates to.
7. The sensor apparatus according to claim 6 , wherein the indicator specifies that the metadata request is a request for at least one of time, geo-location, user identity, a network access point, an active user profile, user activity, speed and acceleration metadata.
8. The sensor apparatus according to claim 1 , wherein the sensor apparatus is further configured to participate in an end-to-end session with a correspondent node of the sensor apparatus.
9. The sensor apparatus according to claim 8 , wherein the metadata request is composed in the sensor apparatus at least in part in dependence of information received in the sensor apparatus from the correspondent node.
10. The sensor apparatus according to claim 1 , wherein the transmitter is configured to transmit metadata requests periodically.
11. The sensor apparatus according to claim 1 , wherein the sensor apparatus comprises a mobile communication device, the apparatus further comprising an antenna operatively coupled to the transmitter.
12. A method, comprising:
receiving sensor data in a sensor apparatus and, using IPv6 addressing, from a correspondent node, a request to subscribe to information of the sensor apparatus;
transmitting, from the sensor apparatus, the sensor data, or data derived at least in part from the sensor data to the correspondent node, and
transmitting, from the sensor apparatus, a metadata request, distinct from the sensor data, to a first node distinct from the correspondent node and distinct from the sensor apparatus,
wherein the metadata request comprises a request that the first node add metadata to the sensor data transmitted from the sensor apparatus and wherein the metadata request does not comprise the requested metadata.
13. The method according to claim 12 , further comprising producing the sensor data by physical measurement in the apparatus and providing it to the receiver internally in the sensor apparatus.
14. The method according to claim 12 , wherein the metadata request comprises a request that metadata be transmitted to the sensor apparatus.
15. The method according to claim 14 , comprising deriving contextual sensor data from the sensor data and the metadata, and causing the contextual sensor data to be transmitted to a second node.
16. The method according to claim 12 , wherein the metadata request comprises a request that metadata be transmitted to a second node.
17. The method according to claim 12 , wherein the metadata request comprises an indicator specifying what kind of metadata the metadata request relates to.
18. The method according to claim 17 , wherein the indicator specifies that the metadata request is a request for at least one of timestamp or geo-location metadata.
19. A sensor apparatus, comprising:
a receiver configured to receive sensor data and, using IPv6 addressing, from a correspondent node, a request to subscribe to information of the sensor apparatus; and
a transmitter configured to cause the sensor data, or data derived at least in part from the sensor data, to be transmitted to the correspondent node,
wherein the transmitter is further configured to transmit a metadata request, distinct from the sensor data, to a first node distinct from the correspondent node and distinct from the sensor apparatus, wherein the metadata request comprises a request that metadata be transmitted to the correspondent node, and wherein the metadata request does not comprise the requested metadata.
20. The sensor apparatus according to claim 19 , wherein the metadata request comprises an indicator specifying what kind of metadata the metadata request relates to.
