On Reliability Metrics for Wireless Sensor Networks Under Stochastic Node Failures

While the Internet of Things promises transformative benefits through ubiquitous connectivity and data-driven intelligence, the realization of this potential is critically dependent on the underlying infrastructure, particularly wireless sensor networks, which serve as the essential component for environmental interaction and information gathering. The dynamic nature of these networks, characterized by node unreliability, stringent power constraints, and unpredictable failures, leads to degraded monitoring performance and compromised data integrity. However, mission-critical applications, such as precision agriculture or intelligent transportation systems, require guaranteed levels of operational reliability. In this paper, we consider the reliability metrics for networks with stochastic node failures. Specifically, we consider a network's ability to maintain functionality despite node failures, which crucially depends on the arrangement of nodes and their interconnections. Thus, we explore the design of fault-tolerant systems, with a focus on reliability metrics that account for network topology characteristics.
