UAVs Reformation Approach Based on Packet Loss in GPS-Denied Environments.

Drone technology, which is employed by a large number of industries and institutions, including the military and commercial, makes use of the Global Positioning System (GPS) to precisely pinpoint locations and has given a huge rise in aerial surveillance applications. Though drones without GPS can still be operated, there is no certainty that the locations are precise due to a lack of real-time position information and existing environmental influences. In this paper, we perform network packet transmission over a drone swarm to relocate imprecise positions of formation when GPS is unavailable. We introduce a reformation approach based on packet loss, which relocates the drone swarm's formation into the initially intended one to preserve the original coverage area as much as possible. Through simulations, we show that our proposed approach guarantees to acquire the lost coverage area by improving inaccurate formation within a reasonable period of time. Although the adjusted formation is not exactly as originally desired in some cases, the coverage area is still higher obtained than the imprecise one.
