Wireless Sensor Network (WSN) consists of distributed independent sensors to find physical or environmental conditions, such as temperature, sound, vibration and pressure to pass their data to each other and through the network to achieve common goal. Hardware of sensor node can be modified easily and it is expensive, so most wireless sensor networks are consist of undefended sensor nodes. WSN's are generally deployed in an environments where an adversary or attacker can easily attack, analyze. To detect the cloned node efficiently Distributed Hash Table (DHT) was proposed.
