20130041993 | SYSTEM AND METHOD FOR PROVIDING WEB SERVICE FOR SMART OBJECTS - A system and method for providing web service for smart objects are provided. The system includes a smart object and a repeater. The smart object receives a web service request for the smart object from a service-requesting user, and transmits a message including information on a web server associated with the web service request to a repeater. The repeater receives the message including the information on the web server associated with the web service request from the smart object, transfers the web service request to the web server and, when a response for the request is received from the web server, transfers the response to the service-requesting user. Accordingly, the present invention can provide a web service to independent of n insufficient memory capacity of a smart object and a limited network. | 02-14-2013 |
