PURPOSE: A wireless network system using an energy saving synchronization method is provided to reduce power consumption of a wireless node, thereby lengthening lifetime of a network. CONSTITUTION: Sensor nodes(120a,120b,120c,120d,120e,120f,120g,120h) wirelessly transmit and receive data. When a sensor node of a sensor network(110) transmits and receives the data, the sensor node periodically or aperiodically synchronizes the data with the sensor node. The sensor node receives the data only during fixed time according to a MAC(Medium Access Control) protocol. The sensor node executes a low-duty cycle operation in a sleep state. |
