Wireless Sensor Network has opened several research criteria related to social security, data management, networking models, distributed system, agricultural aspects, military supervision etc. With the increasing number of applications, an increment in sensor network vulnerabilities has also become noticeably higher. For numerous purposes along with tracing and tracking objects, the sensor nodes with limited power supply, memory usage and computation capability are used to collect data, process it and transmit the generated results to other sensing devices over a specific geographic area. This whole process is done using wireless communication channels which are susceptible to various security threats. Thus securing the WSN has become a great challenge for the researchers.
