A Wireless Sensor Network (WSN) is a collection of thousands of tiny sensor nodes having the capability of wireless communication, limited computation and sensing. These networks are vulnerable to internal and external attacks due to the lack of tamper-resistant packaging and the insecure nature of wireless communication channels. Since most of the existing routing protocols are application specific and hence do not satisfy the security constraints of wireless sensor networks. Whenever, any device comes within the frequency range can get the access to the transmitting data and may affect the transmission.
