Wireless Sensor Network (WSN) is implemented across wide area of applications, including agriculture, defense and so on. A sensor network is a wireless network of the sensors deployed across a wide field, where the objective is to transmit data from the sensor nodes to a central server. As the range of the sensors is very low, and the area of deployment is quite wide, direct data diffusion from sensor to the server is not possible. Therefore multipath routing is adopted in such networks which enable the source sensors to transmit data either through intermediate sensors or special nodes called sink nodes. Due to wireless transmission, data is vulnerable to various kinds of attack.
