Abstract: A media access control device of a medium access control method in a sensor network reducing delay generated between a hop and a sensor node are provided to process data quickly by using a check interval of short length. A first node performs an LPL(Low Power Listening) which is the check interval which is most short among the usable check interval(S510). A first node receiving the downward traffic information determines the check interval by summing the traffic volume which periodically reports to the sink node by summing upward traffic and downward traffic which receives from its own lower nodes(S525). The first node transmits the upward traffic binding update message by using the long preamble of the type '2 fitted to the check interval of the node having the most small traffic(S540).

Abstract: Provided is a method of transmitting/receiving data in a sensor node for reducing overhearing of sensor nodes, and a sensor network which implements the method. A sender node having transmission data from among a plurality of nodes which perform a low power listening (LPL) operation in an asynchronous manner at predetermined time intervals, generates a long preamble including short preambles, each having information including a destination address of the transmission data, a remainder of the long preamble, and a length of the transmission data, and sequentially transmits the second preamble and the transmission data. A receiver node from among the plurality of nodes determines whether a valid signal is sensed during an active state in the LPL operation. If it is determined that the valid signal is sensed, the receiver node receives the short preamble transmitted from the sender node. The receiver node determines a duration time of a deactivated state of the receiver node based on the received first preamble, thereby reducing overhearing in the sensor network.
