Abstract :
A Wireless Sensor Network (WSN) is a versatile sensing system suitable to cover a wide variety of applications. Power efficiency, security and reliability are the major areas of concern in designing WSNs[3][7]. More-over, one of the most important issues in WSN design is to assure the reliability of the collected data which often involve security issues in the wireless communications. This project mainly focused on development of hybrid encryption scheme which combines a symmetric and asymmetric encryption algorithms for secure key exchange and enhanced cipher text security. This paper comments on comparison of performance in terms of bit error rate for symmetric, Asymmetric and hybrid encryption schemes implemented in wireless sensor networks. Test Results shows decrease in bit error rate by using hybrid encryption scheme as compare to symmetric and asymmetric schemes alone. Increase in number of sensors further minimizes bit error rate and improves performance. Alamouti codes with Space time block codes are most widely used transmission mechanism in WSN. Extended space time block codes (ECBSTBC) have better signal to noise ratio improvement when compared with sensor selection scheme. Proposed system uses ECBSTBC codes for transmission[8].
