Intelligent and economical sensors, connected to the network via wireless links and distributed in large quantities, offer unprecedented opportunities to monitor and control homes, cities and the environment. In addition, sensors connected to the network use a wide range of applications within the defence area, generating new features for recognition and surveillance and various tactical applications. Denial of service is one of the most terrible attacks is the cloning attack of the node, where the attacker captures the knot and extracts its secret information, create replicas and enter them in the network field other malevolent behaviour. To detect and mitigate this attack, this paper proposed a Gateway based technique.
