Realizing Fault-Tolerant SHM in WSNs

One important application of wireless sensor networks (WSNs) is event detection: nodes are tasked to determine whether a particular event of interest is occurring in their sensing range. However, when a large number of low-cost wireless sensor nodes are deployed under harsh environment for a long period of time, many of them are likely to exhibit different types of faults. It is important to guarantee that the event of interest is still able to be reliably detected in the presence of faulty nodes.
