Abstract
In the indoor ubiquitous computing environment where Global Positioning System (GPS) cannot be utilized, the approach to calculate the locations of Unmanned Aerial Vehicles (UAVs) is the core technique to control multiple UAVs. To calculate the locations of UAVs, the distance between Access Points (APs) and UAVs should be measured accurately given that the location of UAVs is obtained on the basis of the distance between APs and UAVs. In this paper, we propose a method to measure the distance between a single beacon and a single AP in an indoor ubiquitous computing environment. We assume that the beacon is attached to the bottom of a UAV. In the indoor experiment, while transferring a beacon, the distances between the beacon and an AP were measured and tuned. Therefore, the accumulated difference between the real beacon location and the calculated beacon location was reduced by 31.1 %.
