Wireless Sensor Networks (WSNs) is excellent technology which provides great potential for situations like battlefields and commercial applications such as building, traffic survey, monitoring environments smart homes and many more scenarios. Security is the most important challenge in wireless sensor networks. Sensor networks dose not haves any user control for each individual node and wireless environment. Basically some special security threats and attacks of WSNs get addressed in the authors' paper. Distributed sensor cloning attack will get identified using this model. They implement Zero Knowledge Protocol (ZKP) for the verification of sender sensor nodes. With attachment of unique fingerprint to each node they address the clone attack.
