摘要： 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.

摘要： Provided are a method and apparatus for controlling media access in a sensor network and a method of managing traffic information. Since traffic information is exchanged between nodes and data is transmitted by using a dynamic long preamble according to receiver nodes, data transmission efficiency can be improved, energy consumed to transmit the long preamble can be reduced, and data transmission delay can be reduced as well.

摘要： A method for selecting an access point by considering state information including the number of mobile stations connected in each access point and a traffic amount at each access point is disclosed. The method includes the steps of a) at access points, inserting a first state information of the access point about the number of connected mobile stations into a Beacon frame/Probe Response message frame; b) at the access points, the Beacon frame/Probe Response message frame of the first state information is transmitted to the mobile station; c) at the access points, inserting a second state information about a traffic amount into the Beacon frame/Probe Response message frame; d) at each the access points, the Beacon frame/Probe Response message frame of the second state information is transmitted to the mobile station; and e) at the mobile station, selecting one of access points based on the first and second state information.
