In the current world people are using the sensing
networks called IoT and WSN as the subset of IoT in various
applications. The employment of these sensor networks is rapidly
increasing. Due to the longer usage of these sensor networks
security issues are eventually happening and has the possibility
of developing the attacks in the network. In this review, focuses
on wormhole attacks in wireless sensor network (WSN) and
Internet of Things (IoT) creating a tunnels i.e., wormhole link in
between source and the destination node in the network. The
classification of wormhole attack in both WSN and IoT are
presented based on the mode of attacker. The detection
mechanisms of wormhole attack are specified in both WSN and
IoT. It hypothesizes the detection strength is more in IoT than the
WSN based on the analysis, the parameters of the detection
algorithm that the WSN is about 20% while in IoT is 70%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
