Recent advances in wireless and electronic communications have allowed the implementation of low-cost multifunction sensors, low power consumption and low power consumption, and communicate in a few words. Smart and cheap sensors, connected to the network through wireless connections and distributed in large quantities, offer unprecedented opportunities to monitor and control homes, cities and the environment. In addition, the sensors connected to the network use a wide range of applications within the defense area, generating new functions for recognition and surveillance and various tactical applications. Sybil is one of the most terrible attacks is the cloning attack of nodes, in which the attacker captures the node and extracts its secret information, creates replicas and inserts other malicious behavior into the network. In this document, sink Based detection mechanism (SBDM) have been proposed to detect and mitigate this attack.
