Abstract
A processing device equips a controller that is intended for providing data transmission schedules into multi-slot frames, based on a conflict graph representative of wireless links between nodes that interfere when transmitting simultaneously on a same radio channel, for nodes linked therebetween and belonging to a multi-hop wireless network using a MAC protocol supporting a slotted access. This processing device comprises a processing means arranged, during each frame, for updating the conflict graph from interference information provided by the nodes during this frame, and for refining this conflict graph from detection of hidden interferer nodes based on detected failures of data transmissions of the links between these nodes during at least the previous frame.
