Abstract

Based on the master-slave transmission mode, we proposed a device synchronization method for the light control in ZigBee networks. The lighting devices are distributed over the ground of the road and synchronously flashed at night to improve safety of traffic. Each lighting device is powered by a lithium battery charged by a solar cell during the day. Timing synchronization packets of application layer are periodically sent from the master node to the slaves. When the master node is failure to work, a new master is elected from slave nodes by a free contention rule. The lighting devices still can flash synchronously visually even in the no-master mode or the multi-master mode. Experimental results show the feasibility of our work.
