Protocols for detection of node replication attack on wireless sensor network

Wireless sensor network has many small sensor nodes that work in collaborative manner to achieve a specific task. But it is deployed in unattended environment and that is why it is prone to attacks. These attacks mainly fall into two categories that is application dependent and application independent .In this paper the focus is on the node replication attack which falls under application independent attacks. In this paper a survey has been done related to node replication attack and existing techniques for solving this issue has been studied. The paper mainly focuses on the types of attacks on wireless sensor network and the two techniques centralized and distributed detection for detection of the node replication attack. Defending against this node replication attack is recently become a research topic in the security of wireless sensor network. The applications and advantages of centralized detection and distributed detection and their respective limitations has been studied.
