Better Security for Wireless Sensor Networks

Sensor networks will play a key role in future smart environments. Sensor nodes which are used to form wireless sensor networks, are limited energy resources and have low power capabilities. Thus, sensor networks need to be energy efficient. When they are deployed in military environments, they also need strong security services. In this paper, an improved energy-efficient security scheme is proposed for resource constrained sensor networks. The proposed scheme provides an improved security mechanism to detect energy consuming and useless packets that enemy injects into sensor network. Also, in this paper we present a simple wormhole detection for better security.
