Sensitivity or importance analysis has been widely used for identifying system weaknesses and supporting system improvement and maintenance activities. Despite the rich literature on the sensitivity analysis of many mission‐critical and safety‐critical systems, no existing work has been devoted to wireless sensor networks (WSN). In this paper, we first analyze link and node importance with respect...
Wireless sensor networks (WSN) are being used in a wide range of application areas, such as national security, attack and disaster preparation and response, military surveillance, and medical care. All these applications require a certain level of reliability and security during data transmission. Data loss or corruption in WSN may be due to hardware failures, wireless channel noises, or malicious...
This paper investigates the relationships between infrastructure communication reliability (ICR) of wireless sensor networks (WSN) and different network topology characteristics including connectivity, average path length, average degree, diameter, and clustering coefficient. Based on the binary decision diagrams (BDD)-based method, the ICR of WSN modeled using connected graphs are evaluated. In particular,...
