Abstract

A method for creating a virtual Wireless Sensor Network (WSN) is disclosed. The method includes extracting one or more niceties of a physical WSN and embedding at least one of the extracted niceties in a soft object to represent one or more sensor nodes of the physical WSN. The method includes, sending equivalent command to the one or more sensor nodes of the physical WSN, when one or more changes are performed on corresponding niceties of the soft object. Further, the method adding or deleting one or more niceties corresponding to the one or more sensor nodes from the soft object upon ingress or egress of the one or more sensor nodes in the physical WSN. The method also includes steps of building application using the soft object of the virtual WSN.

Claims

1. A method of controlling sensor nodes, the method comprising:

extracting, with a computing device connected to a Wireless Sensor Network (WSN), WSN information comprising a communication mode used by a plurality of sensor nodes of the WSN to exchange a plurality of packets with a base station, a traversed network path of the plurality of packets, and sensor or control data included in the plurality of packets;

transforming, with the computing device, at least one of the sensor data or the control data into a predefined format;

embedding, with the computing device, at least a portion of the WSN information in an object including at least the transformed at least one of the sensor data or the control data;

updating, with the computing device, the object based on a defined functionality of one or more of the plurality of sensor nodes; and

sending, with the computing device, one or more commands to actuate one or more electrical devices interfaced with the one or more of the plurality of sensor nodes in accordance with the defined functionality and using the updated object.

2. The method as recited in claim 1, wherein the extracting further comprises translating details of the determined communication mode into details of a predetermined communication mode.

3. The method as recited in claim 1, wherein the extracting further comprises segregating at least one of data packets or non-data packets, wherein the data packets include the sensor data and the non-data packets include the control data.

4. The method as recited in claim 1, wherein the traversed network path of the plurality of packets is an optimal path comprising at least one intermediate sensor node or direct communication to the base station.

5. The method as recited in claim 1, wherein the object is in at least one of an XML format, a common separated value (csv) format, or a java object format.

6. The method as recited in claim 1, wherein the updating further comprises generating a Graphical User Interface (GUI) for displaying the object and obtaining one or more user inputs from the GUI.

7. The method as recited in claim 1, further comprising:

adding, with the computing system, corresponding WSN information in the object when one or more new sensor nodes are added in the WSN; and

deleting, with the computing system, corresponding WSN information in the object when one or more existing sensor nodes are removed from the WSN.

8. A non-transitory computer-readable medium having stored thereon instructions for controlling sensor nodes, the instructions comprising machine executable code which, when executed by a processor, causes the processor to perform steps comprising:

extracting WSN information comprising a communication mode used by a plurality of sensor nodes of a Wireless Sensor Network (WSN) to exchange a plurality of packets with a base station, a traversed network path of the plurality of packets, and sensor or control data included in the plurality of packets;

transforming at least one of the sensor data or the control data into a predefined format;

embedding at least a portion of the WSN information in an object including at least the transformed at least one of the sensor data or the control data;

updating the object based on a defined functionality of one or more of the plurality of sensor nodes; and

sending one or more commands to actuate one or more electrical devices interfaced with the one or more of the plurality of sensor nodes in accordance with the defined functionality and using the updated object.

9. The medium as recited in claim 8, wherein the extracting further comprises translating details of the determined communication mode into details of a predetermined communication mode.

10. The medium as recited in claim 8, wherein the extracting further comprises segregating at least one of data packets or non-data packets, wherein the data packets include the sensor data and the non-data packets include the control data.

11. The medium as recited in claim 8, wherein the traversed network path of the plurality of packets is an optimal path comprising at least one intermediate sensor node or direct communication to the base station.

12. The medium as recited in claim 8, wherein the object is in at least one of an XML format, a common separated value (csv) format, or a java object format.

13. The medium as recited in claim 8, wherein the updating further comprises generating a Graphical User Interface (GUI) for displaying the object and obtaining one or more user inputs from the GUI.

14. The medium as recited in claim 8, further having stored thereon instructions comprising machine executable code which, when executed by the processor, causes the processor to perform steps further comprising:

adding corresponding WSN information in the object when one or more new sensor nodes are added in the WSN; and

deleting corresponding WSN information in the object when one or more existing sensor nodes are removed from the WSN.

15. A computing device, comprising:
