Abstract
A method is provided for routing data received during a first time window by a node-forming device of a network having a plurality of nodes suitable for communicating over a wireless communications channel. The method is adapted to select a time slot from a set of predefined time slots in a second time window consecutive with the first time window, to monitor the communications channel between the end of the first time window and the selected time slot in order to detect the presence or the absence of a signal on the channel, and to broadcast the data from an instant of the selected time slot in the event of detecting the absence of a signal and not to broadcast in the event of detecting the presence of a signal. Also provided is a node-forming device that performs the routing method.
