Abstract: The present invention relates to a method for synchronising a node in a deterministic mesh network, in particular a network of sensors using a channel hopping (TSCH) transmission medium access mode. Each node measures the successive synchronisation offsets of its local clock in relation to those of neighbour nodes with which it enters into communication, the measurement being carried out by detecting a reception event of a packet transmitted by the neighbour node or an acknowledgement of a packet transmitted by said node to the neighbour node. The node estimates from these synchronisation offsets, a synchronisation offset for the timeslot and corrects its local clock by a fraction of the synchronisation offset thus estimated. Said fraction may be determined by means of multi-agent reinforcement learning (MARL), each agent being associated with a node of the network.
