Abstract
Wireless sensor networks are now-a-days rapidly developing in the field of science and technology. And it promises to have a large number of applications in next generation networks (NGN). The wireless sensor networks can be easily attacked from various sides and one of the serious attacks faced by the wireless sensor networks is the node clone attack. The node clone attack acts as the basic method to mount a huge insider attack. The cloned nodes must be detected in order to minimize the damages caused by them to the network. To protect the network from the clone attacks is to prevent an adversary from extracting the secret key materials from the captured node. Thus, various protocols were proposed to detect the cloned nodes in the network. To detect the cloned nodes from the network two existing protocols were addressed named as RM (randomized multicast) and XED (extremely efficient detection). In RM, each node broadcasts a location claim to its one-hop neighbors. Then, each neighbor selects randomly witness nodes within its communication range and forwards the location claim with a probability to the nodes closest to chosen locations by using geographic routing. At least one witness node is likely to receive conflicting location claims according to birthday paradox when replicated nodes exist in the network. The key idea of XED is to detect clones by providing the random numbers to the other nodes and asking for random number while meeting the node again. Thus, the cloned nodes will be detected by using the above mentioned protocols.
