The results obtained demonstrate that both implementations are suitable and effective, but also that there are notable differences between them: the Mule-based architecture is faster when the architecture makes use of two message broker topics and compares different types of events, while the WSO2-based one is faster when there is a single topic and one event type, and the system has a heavy workload.José Roldán-GómezJuan Boubeta-PuigGabriela Pachacama-CastilloGuadalupe OrtizJose Luis MartínezPeerJ Inc.articleInternet of thingsComplex event processingMachine learningPattern detectionSecurity attackElectronic computers.
