无线传感器网络可靠性建模方法

摘要

无线传感器网络部署设计的基础就是可靠性,因此,对无线传感器网络可靠性研究已经成为全世界在这个领域中研究的一个重点内容。无线传感器网络可靠性研究的一个有效方法就是建立数学模型。为了能够更好地进行无线传感器网络可靠性的建模,本文先介绍了无线传感器网络结构和节点模型,然后主要对无线传感器网络可靠性建模方法进行分析,提出了K-可靠性模型,并对无线传感器网络系统设计时参考依据进行简单说明。经过实践证明,无线传感器网络的可靠性完全能够通过K-可靠性模型进行测量。%The base of design of wireless sensor network deployment is reliability, so the study of wireless sensor network reliability is very important in this domain all over the world. Reliability study of wireless sensor networks is an effective way is to build a mathematical model. This paper, firstly, introduces the structure and node model of wireless sensor network, secondly, analyses wireless sensor network reliability modeling methods, finally, advances K-reliability model. The practice proves that the reliability of wireless sensor network can be measured through K-reliability model.
