LOW POWER SENSOR NETWORK SYSTEM USING CLUSTER NETWORK AND METHOD FOR ESTABLISHING CLUSTER NETWORK IN SENSOR NETWORK

摘要

PURPOSE: A low power sensor network system and cluster network construction method thereof are provided to reduce the load of a zigbee router by forming a cluster network which is formed with a cluster header. CONSTITUTION: A coordinator(100) executes a gateway role between sensor network and an external network. A high-performance router(110) routes the data of a sensor node to a neighbor node or the coordinator. The neighbor node of the high performance router is operated as a cluster header in a low power router(120). The non-neighbor node of the high performance router is operated as the lower node of the cluster header in the low power router. The cluster header executes a bridge role between the network and a cluster network.
