METHOD FOR IMPLEMENTING MAC LAYER ACCESS, AND SENSOR NODE

摘要

A method for implementing MAC layer access, and a sensor node. The method comprises: a sensor node determines an initial value of a backoff counter according to the number of data packets temporarily stored in a current data queue; and in a process of backoff counting, the sensor node monitors a channel and updates the value of the backoff counter according to the state of the channel until the value of the backoff counter is 0, and the sensor node sends the data packet.
