Abstract

In a network of sensor nodes, operational efficiency may be increased by configuring the sensor nodes so that sensor agents may be transferred to alternative sensor nodes to process sensor node data, such as when the host sensor node is in a low-power mode. A processing node of the network may be configured to retrieve real-time data from a sensor node, but if real-time data is not available, the processing node may perform calculations on cached data retrieved from a processor node cache or data of a nearby sensor node.

Claims

1. A processing node, comprising:

a processing agent configured to;

receive measurement data indicative of a measurement of a first sensor corresponding to a first sensor node;

perform a calculation using the measurement data in response to determining that real-time data is available from the first sensor node; and

perform the calculation using cached data retrieved from the first sensor node in response to determining that the real-time data is not available from the first sensor node; and

a sensor node manager configured to manage the first sensor node in response to the calculation.

2. The processing node according to claim 1, further comprising a cache configured to cache the measurement data from the first sensor node.

3. The processing node according to claim 1, wherein the processing node is further configured to retrieve the measurement data of the first sensor node from a cache of at least one second sensor node.

4. The processing node according to claim 3, wherein the sensor node manager is further configured to identify other sensor nodes available to receive the measurement data corresponding to the first sensor node.

5. The processing node according to claim 1, wherein the sensor node manager is further configured to:

determine an operative state of at least one sensor node; and

instruct the at least one sensor node to transfer a corresponding sensor agent and a corresponding data to an alternative sensor node.

6. The processing node according to claim 5, wherein the sensor node manager is further configured to instruct the at least one sensor node to transfer the corresponding sensor agent and the corresponding data in response to an operative state of the at least one sensor node being in a low-power mode, sleep mode, or stealth mode.

7. A method, comprising:

recording a data measurement from at least one first sensor corresponding to a first sensor node;

processing the data measurement at the first sensor node to generate a result in response to the first sensor node being in a processing mode; and

transferring the data measurement to a second sensor node to generate the result at the second sensor node in response to the first sensor node being in a non-processing mode.

8. The method according to claim 7, wherein processing the data measurement at the first sensor node further comprises directing a first sensor agent to process the data measurement.

9. The method according to claim 8, wherein transferring the data measurement to the second sensor node further comprises directing transferring the first sensor agent to the second sensor node.

10. The method according to claim 9, further comprising:

determining if a second sensor agent is active on the second sensor node; and

deactivating the second sensor agent in response to the determination.

11. The method according to claim 7, wherein transferring the processing of the data measurement to the second node occurs in response to a command.

12. A computer-readable storage device comprising computer-executable instructions stored thereon that configure a first processing node to perform operations comprising:

receiving a data measurement from a first sensor corresponding to a first sensor node;

storing the data measurement in a memory operatively associated with the first processing node;

generating a data message comprising the data measurement; and

communicating the data message to a second sensor node remote from the first sensor node.

13. The computer-readable storage device according to claim 12, wherein the first processing node is configured to perform operations further comprising:

executing a first agent to process the data measurement to produce a result;

generating a result message corresponding to the result; and

transmitting the result message to the second sensor node.

14. The computer-readable storage device according to claim 13, wherein the first processing node is configured to perform operations further comprising:

instructing a first sensor node to generate a first agent archive package comprising the first agent and the data measurement; and

instructing the first sensor node to transmit the first agent archive package to the second sensor node.

15. The computer-readable storage device according to claim 12, wherein the first processing node is configured to perform operations further comprising:

instructing the first sensor node to receive an agent archive package from a second sensor node, the agent archive package comprising a second agent executable by the first sensor node and a second data measurement from a second sensor corresponding to the second sensor node; and

instructing the first sensor node to execute the second agent to process the second data measurement.

16. A sensor node, comprising:

a sensor configured to generate sensor data in response to measuring an event;
