An Efficient Data Gathering Method in UAV-Collaborative Sensing

Abstract

In this paper, we propose a method that achieves efficient data gathering in UAV-collaborative sensing which monitors a target region using multiple autonomous UAVs (Unmanned Aerial Vehicles) owned by different organizations and individuals. Our proposed method defines a metric that evaluates the frequency of exploration for each location based on our previous method [7]. By determining the moving path of each UAV using this metric, our method achieves an efficient exploration of a target region. In addition, our method achieves data gathering to the base stations with a shorter delay by introducing i) periodical returning to the base stations and ii) data sharing between UAVs and base stations via direct wireless communication.
