Method and apparatus for transmitting/receiving data in wireless sensor network
A method and apparatus for transmitting/receiving data in a Wireless Sensor Network (WSN). The method typically includes the steps of: ascertaining characteristics of data whose transfer is requested; ascertaining a Link Quality Indication Value (LQIV); determining a level of a link state in consideration of the characteristics of the data and the LQIV; and controlling the link transfer of the data in consideration of the level of the link state. The apparatus includes a module for transmitting/receiving data in the network layer thereof having a link level determination unit for predefining a level of a link state, depending on characteristics of data and a Link Quality Indication Value (LQIV) to store a predefined level of the link state, and to determine a level of the link state. A link control unit controls the link transfer of the data in consideration of the determined level of the link state.
