Example implementations relate to a method for synchronizing a specific node connected to a plurality of other nodes. The method comprises receiving a respective synchronization quality value for a transmitting other node. The method also comprises measuring a respective propagation medium quality value with the transmitting other node. The method further comprises updating a specific synchronization reference of the specific node, whereby the updating comprises assigning to a respective contribution of the transmitting other node a respective weight of the transmitting other node, the respective weight being a function of the respective synchronization quality value of the transmitting other node and of the respective propagation medium quality value with the transmitting other node. The method also comprises revising a specific synchronization quality value and emitting to a receiving other node the revised specific synchronization quality value.
