Abstract:
1. A sensor node relay comprising: a connecting unit configured to transmit and receive Internet Protocol (IP)-based messages to and from a sensor data collector; an interface configured to connect to one or more Internet-unsupported sensor nodes; a request processing unit configured to create a modified CoAP sensor data request by attaching a shim header above a header of a received CoAP sensor data request, and transmit the modified CoAP sensor data request to one or more of the Internet-unsupported sensor nodes through the interface; and a response processing unit configured to create an IP-based sensor data response including sensor data received from one or more of the Internet-unsupported sensor nodes through the interface and transmit the IP-based sensor data response to the sensor data collector through the connecting unit, wherein creating the IP-based sensor data response includes removing the shim header from a sensor data response received from the one or more of the Internet-unsupported sensor nodes, and wherein the shim header has a format other than an IP header format.
