Security Issues in Wireless Sensor Networks

Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various applications both for mass public and military. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats. The intent of this paper is to investigate the security related issues and challenges in wireless sensor networks. We identify the security threats, review proposed security mechanisms for wireless sensor networks. Finally, we will try to provide a general approach to planning and implementing wireless sensor networks to support the arrays of sensors needed to operate plants, conduct scientific experiments, and test components.
