An Security Algorithm for Wireless Sensor Network

A wireless sensor network is a data communication system that consists of from several to thousands of tiny wireless sensor nodes. These battery powered sensor nodes cooperate with each other to accomplish data transmission. The inclusion of wireless communication technology also incurs various types of security threats. this paper present a review of different routing techniques and security issues. Then the algorithm is proposed using energy-efficient for security problem. Simulation results show that it is to effectively balance the network energy consumption, and is useful for secure wireless data transmission or key distribution in wireless sensor networks.
