通过部署数百或数千个微传感器并组织它们的网络，可以监视和获取环境或对象的信息，以供用户，应用程序或系统使用。由于传感器节点通常由电池供电，因此需要一种节能的数据收集方案来延长传感器网络的寿命。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从传感器网络的边缘传播到基站的传播形成一个同心圆。由于在其节点以不受控制的方式部署的传感器网络中假设任何类型的集中控制都是不现实的，因此传感器节点通过观察其附近的传感器节点发射的无线电信号来独立地确定其同步发射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。我们进行了模拟实验，并验证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，和能源效率的方式。
By deploying hundreds or thousands of microsensors and organizing a network of them, one can monitor and obtain information of environments or objects for use by users, applications, or systems. Since sensor nodes are usually powered by batteries, an energy-efficient data gathering scheme is needed to prolong the lifetime of the sensor network. In this paper, we propose a novel scheme for data gathering where sensor information periodically propagates from the edge of a sensor network to a base station as the propagation forms a concentric circle. Since it is unrealistic to assume any type of centralized control in a sensor network whose nodes are deployed in an uncontrolled way, a sensor node independently determines the cycle and the timing at which it emits sensor information in synchrony by observing the radio signals emitted by sensor nodes in its vicinity. 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. We conducted simulation experiments, and verified that our scheme could gather sensor information in a fully-distributed, self-organizing, robust, adaptive, scalable, and energy-efficient manner.
