Wireless Sensor Networks (WSN) are used to examine and to maintain the physical or environmental conditions like temperature, sound, pressure, etc. and utilized to pass the information through the network to a main location. The wireless networks are bi-directional that helps in controlling and maintaining the sensor activities. Wireless sensor networks are used in many security attacks with false data injection, data forgery and overhearing. A large sensor network with the individual sensor nodes aims on security factor.
