Abstract

Systems, methods and computer program products implementing techniques for real-time monitoring using sensor networks. A system implementing the techniques comprises a business application, a sensor network, and a communication link between the sensor network and the business application. The sensor network includes a plurality of sensor nodes, each sensor node being an electronic device that includes a sensor, a processor, memory, and inter-node communication logic that allows the sensor node to communicate bi-directionally with other sensor nodes in the plurality of sensor nodes, and the sensor network is configured to receive business logic from the business application through the communication link, and to execute the business logic on the sensor nodes.

Claims

1. A computer program product, tangibly embodied in an information carrier, the computer program product being operable to cause data processing apparatus to perform operations comprising:

establishing communication between a sensor node within a sensor network and a business application;

receiving business logic from the business application; and

executing the business logic on the sensor node.

2. The computer program product of claim 1, wherein the business logic includes a set of rules, each rule specifying a condition and an action to be performed when the condition is met.

3. The computer program product of claim 2, wherein the action is to raise an alert.

4. The computer program product of claim 2, wherein executing the business logic includes resolving a rule in the set of rules.

5. The computer program product of claim 4, wherein resolving a rule in the set of rules includes:

replacing a variable in the condition with a sensor value;

determining whether the condition is met; and

if the condition is met, performing the action specified by the rule.

6. The computer program product of claim 1, wherein the operations further comprise:

detecting other sensor nodes in proximity to the sensor node; and

upon such detection, sending a message to the other sensor nodes, the message including an identifier for the sensor node and a sensor value read from the sensor on the sensor node.

7. The computer program product of claim 2, wherein the rules specify storage requirements, the storage requirements including one or more of temperature requirements, humidity requirements, storage time requirements, and storage capacity requirements.

8. The computer program product of claim 1, wherein:

the sensor network is located in a physical storage facility; and

each sensor node is attached to a physical item stored in the physical storage facility.

9. The computer program product of claim 1, wherein the sensor network includes a monitoring node that handles all communication between the sensor network and the business application.

10. A system comprising:

a business application;

a sensor network; and

a communication link between the sensor network and the business application, wherein;

the sensor network includes a plurality of sensor nodes, each sensor node being an electronic device that includes a sensor, a processor, memory, and inter-node communication logic that allows the sensor node to communicate bi-directionally with other sensor nodes in the plurality of sensor nodes; and

the sensor network is configured to receive business logic from the business application through the communication link, and to execute the business logic on the sensor nodes.

11. The system of claim 10, wherein the business logic includes a set of rules, each rule specifying a condition and an action to be performed when the condition is met.

12. The system of claim 11, wherein the action is to raise an alert.

13. The system of claim 11, wherein to execute the business logic includes to resolve a rule in the set of rules.

14. The system of claim 11, wherein to resolve a rule in the set of rules includes:

to replace a variable in the condition with a sensor value;

to determine whether the condition is met; and

if the condition is met, to perform the action specified by the rule.

15. The system of claim 10, wherein the inter-node communication logic is RF (Radio Frequency) logic.

16. The system of claim 10, wherein each sensor node is configured to:

detect other sensor nodes in proximity to the sensor node; and

upon such detection, send a message to the other sensor nodes, the message including an identifier for the sensor node and a sensor value read from the sensor on the sensor node.

17. The system of claim 11, wherein the rules specify storage requirements, the storage requirements including one or more of temperature requirements, humidity requirements, storage time requirements, and storage capacity requirements.

18. The system of claim 10, wherein:

the sensor network is located in a physical storage facility; and

each sensor node is attached to a physical item stored in the physical storage facility.

19. The system of claim 10, wherein the business application is a product lifecycle management application.

20. The system of claim 10, wherein the plurality of sensor nodes includes a monitoring node that handles all communication between the sensor network and the business application.
