论文摘要
传感器网络中信息价值（VOI）的优化整合了通信系统中测量过程的认识。但是，大多数现有的调度算法都不考虑监视应用程序的特定需求，而是将VOI定义为整个系统状态的通用均方根误差（MSE），无论单个组件的相关性如何。在这项工作中，我们考虑了不同的摘要统计数据，即国家的不同功能，这可以代表监视过程的有用信息，尤其是在安全和工业应用方面。我们提出的政策将不同摘要统计数据的估计误差最小化，显示出模拟的显着增长。
The optimization of Value of Information (VoI) in sensor networks integrates awareness of the measured process in the communication system. However, most existing scheduling algorithms do not consider the specific needs of monitoring applications, but define VoI as a generic Mean Square Error (MSE) of the whole system state regardless of the relevance of individual components. In this work, we consider different summary statistics, i.e., different functions of the state, which can represent the useful information for a monitoring process, particularly in safety and industrial applications. We propose policies that minimize the estimation error for different summary statistics, showing significant gains by simulation.
