SENSOR NETWORK AND METHOD FOR COMPOSITION THEREOF

摘要

PURPOSE: A sensor network and a configuring method thereof are provided to replace a battery at a battery replacement time of a sensor node with a small work amount. CONSTITUTION: A gateway(100) transmits data received from the second sensor node to a communication server. The second sensing node senses a current amount according to the use of external power. When the sensed current amount is larger than a reference current amount, the second sensor node releases connection with the first sensor node. The second sensor node communicates with the first sensor node which requests reconnection in consideration of a preset access allowing node number.
