PURPOSE: An adaptive traffic asynchronous transmission system for implementing low power and a method thereof are provided to extend the active state of a duty cycle by transmitting real data without confirming the duty cycle state of a reception sensor node. CONSTITUTION: A sensor unit of a sensor node collects environment data. The sensor unit stores the collected environment data in a data storage unit. A data transmission or reception unit transmits and receives environmental data in the activate state of a duty cycle. When there is the environment data which is transmitted to other sensor nodes through the data transmission or reception unit, a duty cycle management unit extends the activate state of the duty cycle.
