Method. Algorithm and Scenarios of Using a Group of UAVs as Base Stations for a Group of Ground Mobile Agents

The paper proposes a method, an algorithm and scenarios of the use of a group of unmanned aerial vehicles (UAVs) as base stations to provide radio communication for a group of ground mobile agents (GMAs) as part of heterogeneous dynamic technical systems (HDTSs) operating in an intelligent environment. The work gives the mathematical description of the problem of choosing sub-optimal (rational) composition and spatial distribution of the UAV s, and calculating the coverage range (radius) for DAV-DAV and DAV - GMA links respectively. The proposed algorithm allows forming the composition of the DAV group (iteratively) to ensure that the coverage for the GMAs when moving in a given region. The algorithm checks the expediency of moving the D A V s (or their operation in current positions), moves additional DAVs from the base or returns unused DAVs to the base (changes their state to inactive), if necessary. The main tasks to be performed by the HDTS (composed of the groups of DAVs and GMAs) have been determined. The paper proposes several scenarios for the use of the UAVs to ensure radio communications for ground mobile agents. The work offers the requirements to the developed solution as part of the security monitor of a HDTS, including the functionality, a set of target parameters, and the main events/possible failures that can occur during the mission
