SENSOR NETWORK AND METHOD FOR CLUSTERING OF THE SENSOR NETWORK

摘要

PURPOSE: A sensor network and clustering method of sensor network are provided to minimize energy which is consumed from a sensor node which configures a sensor network and to extend the life span. CONSTITUTION: A sink node(110) includes a high-rate radio interface transmitting and receiving data to the high-rate. A plurality of dual radio nodes(121-124) includes a high-rate radio interface and a low-rate radio interface. The low-rate radio interface transmits and receives data to low-rate. Several dual radio nodes transmits and receives data according to a hop-by-hop method by using the high-rate radio interface.
