Teams can verify network state before and after network changes to ensure smooth deployment of the changes. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Besides the introduction of complex computational requirements, WSNs also have been proposed to operate in environments different from terrestrial ones. A WSN consists of spatially distributed autonomous devices that use sensors to detect temperature, sound, and other parameters in different applications. The requirement and consequences of the complete integration of the Internet and WSN are still under study (Alcaraz, Najera, Lopez, & Roman, 2010). Furthermore, the transmission power level can be kept low, which is highly desirable in covert operations.
