Apparatus for performing a low-power routing method, and this, using a time synchronization method and a reservation technique in a wireless sensor network,

Discloses a device for performing a low-power routing method, and this, using a time synchronization method and a reservation technique in a wireless sensor network. In the wireless sensor network time synchronization method, the second synchronization request has a transmission time value of a pre-set sync area period and receiving a first synchronizing request instruction packet from the parent node to manage the synchronization, the first synchronization request command of receiving a command packet from the parent node and the first synchronization request command packet reception time and the second synchronization request command packet reception time and a child using the transmission time value of a packet of the first sync request command of the node and a step of performing the time synchronization. Sensor network, low power consumption, routing (routing), sync (synchronization)
