Abstract
A data communication method implemented by a sensor node of a telecommunications network including a plurality of sensor nodes and a concentrator node, which share a communication channel. The method includes: selecting a time interval in a contention window including a plurality of time intervals and preceding a transmission period including a plurality of transmission intervals; emitting a request signal during the selected time interval to the concentrator node; receiving a response signal carrying encoded information representing an ordered combination of the intervals marked during which the signals were received by the concentrator node; determining a transmission rank according to a number of intervals marked by the concentrator node; and deciding to emit data to the concentrator node in the transmission period when the transmission rank is lower than or equal to the number of intervals of the transmission period.
