This method, however, requires considerable volumes of internal memory for any WSN node on which such detection algorithms are supposed to be implemented.enAll EPiC volumes are open access.Wireless sensor networksWSN reliabilityWSN integrityWSN safety and securityWSN trustworthinessNode replication attacksIntrusion detectionProbabilistic finite automataRandomised detection algorithmDetection accuracyMemory requirementsWireless sensor network (WSN)Article
