One fundamental question for wireless power transfer technology is the energy provisioning problem, i.e., how to provide sufficient energy to mobile rechargeable nodes for their continuous operation. Most existing works overlooked the impacts of node speed and battery capacity. However, we find that if the constraints of node speed and battery capacity are considered, the continuous operation of nodes...
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. Our work takes the first attempt to explore the deployment strategy to achieve full-view barrier coverage with rotatable camera...
