Full-veiw Barrier Coverage In Rotatable Camera Sensor Network

Camera sensors can collect visual information from regions of interest(RoI) and provide more information to classify the intruder. In practice, randomly deployed camera sensors can not guarantee that the barrier is full-view covered, and lead to a waste of sensing resources. We show that deploying camera with rotating ability can improve the utilization of camera sensors. Our work takes the ?rst attempt to explore the deployment strategy to achieve full-view barrier coverage with rotatable camera sensors. We propose a method to select camera sensors from an existing and arbitrary deployment and determine their orientation to obtain a full-view barrier coverage. Our simulation results demonstrate that our algorithm outperforms existing algorithms for?xed directional camera sensors in saving the number of camera sensors.
