Sensor network made by the integration of sensor, micro-electro-mechanism system and network technologies, is a novel technology for acquiring and processing information and has a wide development future. Time synchronization has been an extremely difficult issue for wireless sensor networks due to its decentralized nature. The information exchange of the existing time synchronization protocol leads to excessive consumption of energy and the need of high-level protocol. So a new time synchronization algorithm is proposed based on PCO, which effectively removes high-level interference by the interaction of physical layer, achieves time synchronization, and finds the relationship between wireless sensor networks energy consumption and the synchronization time. The simulation results show that the time synchronization protocol is feasible. It’s important for the development of WSN.
