Abstract

3 Abstract: Wireless Sensor Networks (WSNs) offer an excellent opportunity to monitor environments, and have a lot of interesting applications, some of which are quite sensitive in nature and require full proof secured environment. The security mechanisms used for wired networks cannot be directly used in sensor networks as there is no user-controlling of each individual node, wireless environment, and more importantly, scarce energy resources. In this research, we consider a typical threat known as clone node attack, where an adversary creates its own low-cost sensor nodes called clone nodes and misinforms the network to acknowledge them as legitimate nodes. To instigate this attack, an adversary only needs to physically capture one node, and after collecting all secret credentials, an adversary clones the sensor node and deploys one or more clones of the compromised node into the network at strategic positions, damaging the whole network by carrying out many internal attacks. Detecting the node clone attack has become an imperative research topic in sensor network security, and designing detection schemes against node clone attack involves different threatening issues and challenges. In this review, we have classified the existing detection schemes and comprehensively explore various suggestions in each category as to demonstrate limitations of the existent detections as well as effective contributions.
