Dynamic detection of node replication attacks using X-RED in wireless sensor networks

Wireless Sensor Networks often deployed in hostile environments, where an attacker can also capture some nodes. Once a node is captured, the attacker can re-program it and start replicating the node. These replicas can then be deployed in all the network area to render malicious attacks. For any node replication detection protocol, the three most important design issues are memory usage, detection probability and energy consumption. Previous node replication detection schemes either incur more traffic in the network or large memory overhead. We propose a novel dynamic technique for detecting replication attacks using X-RED. X-RED achieves high detection probability and reduces memory overhead than the previously distributed schemes.
