Abstract: A wireless sensor network and a method for configuration thereof are includes a plurality of sensor nodes and a sink node. The network configuration method includes collecting location information about the sensor nodes by the sink node, setting the sensor nodes, which have sensing regions include a transmitting region of the sink node, to an active node based on the location information, and configuring a network composed of the active nodes. Dead nodes are detected by the sink node, and inactive nodes are activated to reconfigure the network as needed due to the detected dead nodes.
