Real-world Deployment of a Smart and Green Wireless Sensor Network for Intrusion Detection

Intrusion detection is one of the most challenging applications in this research field of Wireless Sensor Networks(WSN). It combines challenges of minimizing false positives and negatives as well as those optimizing WSN lifespan. In this paper we present the design and the deployment of a smart and green wireless sensor network for intrusion detection. Our system considers surveillance zone as a set of detection areas. Each area contains a set of sensor nodes related to each other and collaborating with each other in order to reduce false positives and false negatives under the supervision of a correlation node. The correlation node orchestrates area events to send alarms only when a true intrusion occurs and detects faulty nodes thanks to reputations parameters. We tested our proposition with FreeRTOS based simulator we developed and real-world nodes. Results of simulations as well as those of the real-world deployments show that our proposal improves energy consumption and intrusion detection efficiency.
