Abstract
Low energy consumption is one of the important technical requirements of time synchronization algorithm of wireless sensor network. In order to reduce energy consumption, a greatly low energy consumption time synchronization algorithm for wireless sensor network is proposed, named LECTS. This algorithm, which is based on the base mechanism of TPSN, improves in two phases at the same time to reduce energy consumption. In the level discovery phase, it uses the distance between nodes limits part of nodes broadcast to reduce the packets send. Meanwhile, in the synchronization phase, combining unidirectional reference broadcast and pair-wise mechanism, only one node in broadcast domain needs time synchronization, and also greatly reduces the messages. The simulation results show that the algorithm greatly reduces lots of broadcasting packets and exchanges messages for time synchronization of wireless sensor networks, and node density is greater, the energy conservation is more remarkable.关键词
