Node apparatus and method for beacon scheduling over ad-hoc network and data transmitting method thereof

In the ad-hoc (ad-hoc) networks discloses a beacon scheduling node apparatus and a scheduling method and a data transmission method using the same. Ad-hoc (ad-hoc) in a method for reducing the power consumption is rapidly of nodes a data communication frequent progression network, self checking the remaining amount of power of the node that transmits a beacon (beacon), the remaining power amount reference value to inform the scheduled change the beacon transmission interval of the node to another node, and increases the beacon transmission interval of the predetermined node changes and transmits the beacon transmission interval increased for the beacon or less. Which it is able to dynamically change the beacon transmission based on their power state being able to extend the life time of the node, so that the overhead for re-organizing the sensor network can be reduced.
