DEVICE AND METHOD FOR SUPPORTING INTERNET-BASED SENSOR DATA TRANSMISSION

摘要

Provided is a method of supporting CoAP-based sensor data transmission between a sensor data collector in a sensor node relay and one or more 6LoWPAN-unsupported sensor nodes. The method includes receiving a CoAP sensor data request message from the sensor data collector, transmitting a CoAP sensor data request message to a corresponding 6LoWPAN-unsupported sensor node by analyzing the received CoAP sensor data request message, and responding to the sensor data collector by creating a CoAP sensor data response message including sensor data received from one or more of the 6LoWPAN-unsupported sensor nodes.

1. A sensor node relay comprising:
a connecting unit that can access the Internet and transmits and receives an Internet-based message to and from a sensor data collector; an interface that connects one or more Internet-unsupported sensor nodes; a request processing unit that transmits a CoAP sensor data request message to one or more of the Internet-unsupported sensor nodes through the interface by analyzing the CoAP sensor data request message received from the sensor data collector through the connecting unit; and a response processing unit that creates a sensor data response message including sensor data received from one or more of the Internet-unsupported sensor nodes through the interface and transmits it to the sensor data collector through the connecting unit.
