Reliability analysis of a wireless sensor network based on a physical model

Abstract

Wireless sensor networks (WSNs) are task-oriented networks. Reliable data delivery is one of their important goals. Both node failures and communication mechanisms influence reliable data delivery. However, reliability analysis based on graph models is very difficult due to the dynamic topology and distributed nature of a WSN with thousands of nodes. By decomposing the reliability problem into sub-problems, this article presents a new method for analyzing the reliability of a WSN based on a physical model. The presented method is also distributed and flexible.

無線傳感器網絡是任務型網絡 ， 可靠的數據傳輸是其重要目標 ， 節點失效和通信機理都影響數據的可靠傳輸 ， 然而由於傳感器網絡具有節點數量多 ， 拓撲結構動態變化,分布式特點 ， 使得基於圖模型的可靠性分析變得困難 ， 通過將傳感器網絡可靠性問題分解為一些子問題 ， 本文給出一種新的基於物理模型的無線傳感器網絡可靠性分析方法 ， 該方法也具有分布式和靈活的特點。
