  Abstract

Recently, multi-hop network relay nodes can not only operate as simple amplifiers, but also acquire, process, and transmit neighboring signals. In addition, the nodes provides the scheduling for energy saving and data fusion by collaborating with other nodes. For those operations of nodes, the time synchronization among nodes is very necessary function. The time synchronization methods for multi-hop networks in previous works have been based on the one-to-one time synchronization scheme, which periodically repeats the synchronization process between neighbor nodes in a serial manner. The methods have the basic problem that the setup time for the time synchronization increases as the number of nodes increases due to the redundant transmissions of time synchronization messages between nodes. This paper proposes a broadcast time synchronization method to reduce the time synchronization setup time in multi-hop networks with nodes connected serially. Experimental results show that the synchronization setup time is reduced by 8% in the node number increase condition and 16% in the node to node processing delay time increase condition, compared to IEEE 1588 through the broadcast time synchronization mechanism.
