Abstract

We discuss a novel control methodology for power management in heterogeneous distributed sensor networks. We present an event based control optimization formulation of the resource management problem and discuss a method to adaptively change the desired system performance of the sensor network in response to events. This functionality is critical in field-deployable sensor networks where continuous operation is expensive and system adaptation is critical for extended operation in the face of dynamic external events. We show results on various synthetic heterogeneous sensor networks where only partially accurate information about the sensing system is available and illustrate the efficacy of the control algorithm in handling such incorrect models with a negligible increase in transmission of the optimal control settings. We show that the run-time performance of the control algorithm scales quadratically with increasing number of sensors.
传感器网络中连续无线监测的动态控制与电源管理算法
我们讨论了一种用于异构分布式传感器网络电源管理的新型控制方法。我们提出了一种基于事件的资源管理问题的控制优化公式,并讨论了一种自适应改变传感器网络期望系统性能以响应事件的方法。这种功能在现场可部署的传感器网络中是至关重要的,因为连续运行是昂贵的,系统适应对于面对动态外部事件的扩展操作至关重要。我们展示了各种合成异构传感器网络的结果,其中只有关于传感系统的部分准确信息可用,并说明了控制算法在处理这种不正确模型时的有效性,而最优控制设置的传输增加可以忽略不计。结果表明,随着传感器数量的增加,控制算法的运行时性能呈二次增长。
