Abstract
In order to perform synchronization and compensate clock drift among a plurality of communication devices interconnected to form a mesh communications network, all communication devices, except one given communication device, perform a first distributed consensus-based synchronization. The given communication device performs: obtaining a first correction information derived at least from a difference between a clock timing resulting from the first distributed consensus-based synchronization and a reference clock timing; and transmitting the first correction information through the mesh communications network. All the communication devices, except said given communication device, further perform updating the clock timing resulting from the first distributed consensus-based synchronization by taking into account the transmitted first correction information.
