A Novel Attack Detection in Wireless Sensor Networks by Using Sequential Probability Ratio Test

摘要

The main objective of this project is to give security against attacks in the Wireless Sensor Networks (WSNs).One of the most vexing problems in wireless sensor network security is the node Clone attack. In this attack, an adversary breaks into a sensor node, reprograms it, and inserts several copies of the node back into the sensor network. Cloning gives the adversary an easy way to build an army of malicious nodes that can cripple the sensor network. A few distributed solutions to address this fundamental problem have been recently proposed. However, these solutions are not satisfactory. Therefore first, the desirable properties of a distributed mechanism for the detection of node Clone attacks have been analyzed. Second, the known solutions for this problem do not completely meet our requirements. In this work, we propose a fast and effective mobile replication node detection scheme using Sequential probability Ratio Test..
