UAV-assisted Multiband WSN Coverage Evaluation

Integration and deployment of Wireless Sensor Networks (WSNs) in the real world require careful planning of node placement. The wireless link performance is an important factor for the deployment cost as it influences the number of nodes required to achieve the required coverage. Although the coverage can be simulated beforehand through various propagation models, modelling a complex real-world WSN deployment location is prone to omitting performance influencing factors. In this paper, we present the usage of Unmanned Aerial Vehicles (UAVs) to determine the wireless link coverage based on actual measurements for WSN deployments. We show the challenges and exemplary results of our approach through measurements on a typical deployment site for two different frequency bands.
