无线传感器网络构成了与国家安全，监视，军事，医疗保健和环境监测有关的广泛应用的平台。传感器覆盖率问题最近受到了越来越多的关注，这是由于最近负担得起且有效的集成电子设备的进步而大大推动了关注。这个问题围绕一个基本问题：传感器观察物理空间的程度如何？由于各种传感器及其应用，覆盖范围的概念受到广泛的解释。根据要涵盖的主题（区域与离散点）和传感器部署机制（随机与确定性）以及其他无线传感器网络属性（例如，网络连接和最小能源消耗），提出了不同的覆盖范围公式。在本文中，我们调查了在静态无线传感器网络中解决节能覆盖问题的最新贡献。我们介绍了各种覆盖范围，它们的假设以及提出的解决方案的概述。 （c）2005 Elsevier B.V.保留所有权利。
Wireless sensor networks constitute the platform of a broad range of applications related to national security, surveillance, military, health care, and environmental monitoring. The sensor coverage problem has received increased attention recently, being considerably driven by recent advances in affordable and efficient integrated electronic devices. This problem is centered around a fundamental question: How well do the sensors observe the physical space? The coverage concept is subject to a wide range of interpretations due to a variety of sensors and their applications. Different coverage formulations have been proposed, based on the subject to be covered (area versus discrete points) and sensor deployment mechanism (random versus deterministic) as well as on other wireless sensor network properties (e.g. network connectivity and minimum energy consumption). In this article, we survey recent contributions addressing energy-efficient coverage problems in the context of static wireless sensor networks. We present various coverage formulations, their assumptions, as well as an overview of the solutions proposed. (c) 2005 Elsevier B.V. All rights reserved.
