Information-Driven Dynamic Sensor Collaboration for Tracking Applications 论文

摘要

This article overviews the information-driven approach to in ad hoc 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.
