Abstract—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 energy-efficient security protocol is proposed for resource constrained sensor networks. The proposed protocol provides a security mechanism to detect energy consuming and useless packets that enemy injects into sensor network. Both mathematical analysis and simulation of this protocol are provided in this paper.
