Abstract
A method for synchronizing nodes of a multi-hop network with a Time Division Multiplex Access scheme (TDMA), the nodes being hierarchically arranged in different levels, including a step of organizing the TDMA by periodic superframes, the respective superframe having a number of frames including at least a broadcast frame, a step of providing the respective broadcast frame with a number of slots, the number of slots being equal to a number of parent nodes in the multi-hop network, a step of assigning each parent node one slot in the broadcast frame in dependence on its level, and a step of distributing a synchronization information to the parent nodes by means of the broadcast frame, respectively.
