In order to limit this to happen, alerting and prevention systems have been developed, based on different sensors. Therefore, by using these sensor data, drivers alerting signs can be actuated, in order to warn the likely presence of animals crossing the road. A Wireless Sensor Network (WSN) infrastructure can be used and in particular each sensor node should be equipped with different sensors (e.g. ultrasonic, radar, PIR) to effectively detect the presence of moving animals approaching the road. In this way, different finite-size sensing/warning areas are deployed along the road. In addition, the well-known WSN features (e.g. scalability, configurability) allow us to deploy the monitoring system in a great variety of scenarios. In addition, once the presence of a moving target (i.e. animal) has been detected, the actuator node has to be powered in order to advertise the dangerous situation. M1 - masters ER -
