DATA TRANSMISSION METHOD FOR CONSIDERING QOS AND ENERGY CONSUMPTION IN WIRELESS SENSOR NETWORK

摘要

The present invention relates to a method for transmitting data in a wireless sensor network, and more specifically, to a data transmission method for minimizing the energy which is consumed for data transmission under the limited resource conditions of the wireless sensor network, and for satisfying requested reliability and a requested transmission delay value. According to the present invention, the method for transmitting the data in the wireless sensor network determines a data transmission path by considering both QoS and energy consumption in accordance with the data transmission, thereby transmitting the data and satisfying the QoS which is requested in the wireless sensor network that has limited energy sources. Further, according to the present invention, the method for transmitting the data in the wireless sensor network determines an optimal transmission path with little energy by meeting the QoS requirements and determining, through an approximation method, a path for minimizing the energy which is consumed for the data transmission.
