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.
