Abstract
Provided is a Media Access Control (MAC) technology that may improve a data transmission performance in an asynchronous sensor network. The MAC technology may increase a waked-up time interval of a reception node to thereby continue to receive traffic from a transmission node, and change a frequency band where data is transmitted and received to thereby reduce occurrence of collision. Also, when the wake-up time interval of the reception node is similar to a wake-up time of a neighboring node, the wake-up time interval of the reception node may be moved to another time interval, thereby improving the data transmission performance.
