本文概述了信息驱动的方法,在ad hoc传感器网络中的传感器协作。其主要思想是一个网络,以确定参与者的“传感器协作”,通过动态优化的信息效用的数据为一个给定的通信和计算成本。引入了信息效用的定义,并基于计算易处理性的原因,提出了信息效用的几种近似度量。我们说明了这种方法的使用跟踪应用程序的例子。
This article overviews the information-driven approach to sensor collaboration in ad hoc sensor networks. The main idea is for a network to determine participants in a "sensor collaboration" by dynamically optimizing the information utility of data for a given cost of communication and computation. A definition of information utility is introduced, and several approximate measures of the information utility are developed for reasons of computational tractability. We illustrate the use of this approach using examples drawn from tracking applications.
