Terminal in wireless sensor network and method for transmitting data thereof

The invention and the process for setting the terminal and relates to its data transmission method, data generated when a carrier sensing (carrier sensing) the number of Ns and the backoff value of W in a wireless sensor network, and determine the channel is idle, the channel idle when returned to the process, and, W is a wait at the back channel idle verification process for a period of time by transmitting the data generated is zero, W is not equal to 0, W / (Ns-1) slot, to determine whether W is 0, it involves. According to the invention, it is possible to utilize the prior art of the IEEE 802.11 channel connection with excellence in IEEE 802.15.4 energy efficiency. That is, the present invention can perform the carrier sensing less than IEEE 802.11 and this by reducing the time spent in the channel connection from the IEEE 802.15.4 channel access efficiency is increased, to maximize energy savings. A wireless sensor network, back off, carrier sensing, channels, data
