WIRELESS SENSOR NETWORK AND CLUSTERING METHOD FOR THE SAME

摘要

A wireless sensor network and a clustering method therefor are provided to minimize the energy required for transmitting data, which is collected by sensor nodes, to a base station. A sensor field(400) comprises a plurality of sensor nodes. The sensor nodes operate as one among a cluster head and a cluster node. A base station(420) connects a sensor field to an external network, and receives data which is collected from the sensor field, from the cluster head.
