摘要
根据无线传感器网络(WSN)时钟同步机制的作用及研究现状,针对大规模无线传感器网络提出了基于PCO同步模型的无线传感器网络时钟同步算法。由于PCO模型同步机制的可扩展性极好,可以有效地消除上层干扰,可以只通过物理层的相互作用有效地完成同步,因此它非常适用于大规模无线传感器网络的时间同步。
This article introduced the function and the research presently to time synchronization of Wireless Sensor Network. It proposed a time synchronization protocol for dense Wireless Sensor Network which is based on PCO synchronized model. This protocol＇ s extendibility is extremely good; and it can effective eliminate the upper formation disturbance ; also it can effective completes the synchronization through the physical level＇s interaction only, so it is suitable for time synchronization of dense Wireless Sensor Network.
