Network device and data transmission method thereof in wireless sensor network
A wireless sensor network and data transmission method thereof provides for improving channel access efficiency and energy saving effect by using inventive carrier sensing mechanism. The data transmission method includes assessing a channel after initializing, when a packet to be transmitted is generated, a number of carrier sensing attempts (Ns) and a backoff value (W); determining, when the channel availability is assessed to be idle, whether W reaches 0; transmitting the packet if W reaches 0; and reassessing, if W does not reach 0, the channel after a duration corresponding W/(Ns-1) slot.
