Wireless Sensor Networks (WSNs) are growing extremely and becoming more and more attractive for a variety of application areas such as surveillance of information, industrial secrets, air pollution monitoring, area monitoring, and forest fire detection, home automation, industry monitoring, and many more. As WSN is mostly used for gathering application specific information from the surrounding environment, it is highly essential to protect the sensitive data from unauthorized access. WSNs are vulnerable to various security attacks because of broadcast nature of radio transmission. The primary weakness shared by all wireless application and technologies is the vulnerability to security attacks/threats.
