Optimized Replica Node Attack Detection Technique in Wireless Sensor Networks Using Hypothesis Testing . (original) (raw)

In wireless sensor network, there are number of small sensor nodes, this sensor nodes are organized into clusters and send some report to base station. An attacker can capture sensor nodes and can compromise sensor nodes. Then would create duplicate nodes and built up various attacks network. This is happened because of unattended nature of wireless sensor network. These attacks helps attacker to control few more nodes to have control over the network. There are many node replication attack dete which have been used to secure from attacks in the sensor network where nodes are static. These methods are dependent on fixed location of sensors and hence do not works for sensor network where nodes are mobile. In this method basic idea is used that mobile node never have more speed than system speed. In this work, an optimized replica node attack detection technique in wireless sensor networks by using hypothesis testing.
