在无线传感器网络中，成百上千的微型传感器以不受控制的方式被部署以监测和收集环境信息。传感器节点具有有限的功率、计算能力、存储器和通信能力。在本文中，我们提出了一种新的数据收集方案，传感器信息周期性地传播，没有任何集中控制的传感器网络的边缘到基站的传播形成一个同心圆。传感器节点通过观察其附近的传感器节点发出的无线电信号，独立地确定其同步地发出传感器信息的周期和定时。为此，我们采用了脉冲耦合振荡器模型的基础上，生物相互同步，如使用闪烁的萤火虫，鸣叫蟋蟀，和起搏细胞。通过仿真实验，我们证实了我们的计划可以收集传感器信息，在一个完全分布式的，自组织的，鲁棒的，自适应的，可扩展的，和节能的方式。
In wireless sensor networks, hundreds or thousands of microsensors are deployed in an uncontrolled way to monitor and gather information of environments. Sensor nodes have limited power, computational capacities, memory, and communication capability. In this paper, we propose a novel scheme for data gathering where sensor information periodically propagates without any centralized control from the edge of a sensor network to a base station as the propagation forms a concentric circle. By observing the radio signals emitted by sensor nodes in its vicinity, a sensor node independently determines the cycle and the timing at which it emits sensor information in synchrony. For this purpose, we adopt a pulse-coupled oscillator model based on biological mutual synchronization such as that used by flashing fireflies, chirping crickets, and pacemaker cells. Through simulation experiments, we confirmed that our scheme can gather sensor information in a fully-distributed, self-organizing, robust, adaptable, scalable, and energy-efficient manner.
