Abstract

A gateway connected to a Wireless Sensor Network (WSN) for transfer of data with the WSN includes a data reader interface configurable to read sensor data from the WSN received from a communication port connected to the WSN, irrespective of a type of hardware or software used in the WSN. The gateway also includes an application profile interface configurable to receive the sensor data read by the data reader interface and convert the received data into a generic read data message irrespective of the type of hardware or software used in the WSN and a data handler interface configured to receive the generic read data message, process the received generic read data message based on a customized requirement or a standard requirement for the sensor data and send the processed data to a back-end network.

Claims

1. A gateway connected to a Wireless Sensor Network (WSN) for transfer of data with the WSN, the gateway including:

a communication port connected to a WSN;

a communication port connected to a back-end network;

a data reader interface configurable to read sensor data from the WSN received from the communication port connected to the WSN, irrespective of a type of hardware or software used in the WSN;

an application profile interface configurable to receive the sensor data read by the data reader interface and convert the received data into a generic read data message irrespective of the type of hardware or software used in the WSN; and

a data handler interface configured to receive the generic read data message, process the received generic read data message based on a customized requirement or a standard requirement for the sensor data and send the processed data to the back-end network via the communication port connected to the back-end network.

2. The gateway of claim 1, wherein the gateway is configured to receive data from the back-end network destined for the WSN as a generic write data message, the application profile interface is configured to convert the received generic write data message into data suitable for the WSN, and the data reader interface is configured to receive the converted data and transfer the converted data to the WSN.

3. The gateway of claim 1, wherein the data reader interface includes a generic data reader class, the generic data reader class being configurable to read data from any WSN, irrespective of a network type via one or more network-specific data readers.

4. The gateway of claim 3, wherein the network-specific data readers include standard network data readers.

5. The gateway of claim 3, wherein the network-specific data readers include customized network data readers.

6. The gateway of claim 1, wherein the application profile interface is configured to convert the received data based on information within the received data by using a corresponding application profile.

7. The gateway of claim 6, wherein the corresponding application profile is a standard application profile.

8. The gateway of claim 6, wherein the corresponding application profile is a customized application profile.

9. The gateway of claim 1, wherein the data handler interface includes a generic data handler class, the generic data handler class being configurable to process and transfer data to an internal or external subsystem based on a customized requirement or a standard requirement of a user of the WSN.

10. A method of performing transfer of data between a Wireless Sensor Network (WSN) and a back-end network, the method comprising:

receiving sensor data from a WSN;

reading the received sensor data using a data reader interface configurable to read data received from the WSN irrespective of the type of hardware or software used in the WSN;

converting the read data into a generic read data message by using an application profile interface configurable to convert the read data irrespective of the type of hardware or software used in the WSN; and

transferring the generic read data to a back-end network.

11. The method of claim 10 further including:

receiving data from a back-end network as a generic write data message, the received data being destined for the WSN;

converting the generic write data message into data suitable for the WSN by using an appropriate application profile interface based on the WSN; and

transferring the converted data to the WSN by using an appropriate data reader interface based on the WSN.

12. The method of claim 10, including reading the sensor data using a generic data reader class that inherits attributes of the data reader interface, the generic data reader class being configurable to read data from any WSN, irrespective of a network type, via one or more network-specific data readers.

13. The method of claim 12, wherein the network-specific data readers include standard network data readers.

14. The method of claim 12, wherein the network-specific data readers include customized network data readers.

15. The method of claim 10, wherein the converting the read data into a generic read data message includes determining an appropriate application profile that inherits attributes of the application profile interface by extracting information from the read data, the extracted information indicating the appropriate application profile.

16. The method of claim 15, wherein the converting further includes:

extracting sensor data by using the determined application profile;

converting the extracted sensor data into appropriate engineering units; and

populating at least a portion of a generic read data structure with the converted data to form the generic read data message.

17. The method of claim 15, wherein the application profile is a standard application profile.

18. The method of claim 15, wherein the application profile is a customized application profile.

19. A Wireless Sensor Framework for transfer of data between one or more Wireless Sensor Networks and a back-end network, the framework including:
