With the advent of powerful and efficient wireless sensor nodes, the usage of Wireless Sensor Networks (WSN) has been increased greatly. Sensor networks consist of a network of autonomous sensors that can reconfigure themselves so as to sense the environment in the most efficient manner. These nodes are having low power and limited range. Low power implies limited battery life. In WSN, to perform the task successfully low energy consumption is the major concern. Wide use of WSN in practical application makes it necessary to maintain the network security. IP or MAC addresses are used for sender authentication which can be spoofed easily. This makes these types of networks vulnerable to many identity-based attacks.
