Ground Control System Based Routing for Reliable and Efficient Multi-Drone Control System

Abstract

Various unmanned aerial vehicles (UAVs), also called drones, have developed based on advances in hardware and software technologies. Thus, service providers in diverse areas have tried to utilize drones to create more effective solutions. In many cases, employing multiple drones is more effective to perform the given mission than using a single drone. To utilize multiple drones, the drones should be strongly connected, but it is not trivial to construct reliable and efficient networks for drones due to their high mobility. Therefore, we propose a ground control system (GCS) routing protocol (GCS-routing) to overcome this limitation and provide reliable and efficient multi-drone control system, where GCS-routing maximizes GCS utilization. GCS is the essential component of flying ad-hoc network (FANET) and can obtain information about drones. Using this information, GCS-routing can provide more effective routing, predict any topology changes, and react immediately. GCS-routing does not issue any periodic HELLO message for neighbor discovery or link cost estimation, which significantly enhances network performance. We implemented GCS-routing on real drones, and applied GCS-routing to actual drone fleets, as well as simulations to evaluate GCS-routing performance. The results clearly identify the advantages of the proposed routing protocol for drone networks compared with current routing protocols.

Performance Evaluation of Multi-UAV Network Applied to Scanning Rocket Impact Area

“…The ZigBee protocol is used by Mushtaq et al [28], Min and Nam [29] to perform fly-by-sensors (FBS) flight control with stable flight formation, while Sineglazov and Daskal [30] propose a UAV navigation system for dense urban areas in tunnels or indoor environments. The flight planning and formation model is discussed in Lee et al [31], Park et al [32] where an effective routing protocol for navigation control and an information sharing system with onboard sensors and flight path formation algorithms are proposed for various UAVs. Popescu et al [18] propose an optimized trajectory design to avoid restricted regions aiming at bypassing them through close preset landmarks.…”

The Use of Emerging Technologies DIoT: Elderly Daily Living in Post-Epidemic Era

“…When an UAV contacts with GCS, the station monitors the flight status of the UAV with the data of distance, location, altitude, and status of UAV as well as its components [27,29]. In order to achieve a particular task, the GCS is required to establish a highefficient communication with the UAV device via a reliable channel during the remotelycontrolled performance [30]. In that direction, the communication protocol used vitally plays its role in the UAV flight.…”

An MPTCP-Based Transmission Scheme for Improving the Control Stability of Unmanned Aerial Vehicles

“…A UAV can be equipped with a small computing board, which enables a variety of tasks, such as collaboration with existing applications [ 4 ], rapid object delivery [ 5 ] or a wide range of information gathering or sharing tasks [ 6 , 7 ]. UAVs for specific tasks are often managed by a ground control system (GCS) rather than being controlled by each operator one by one [ 8 , 9 ]. In order for the GCS to control the UAV, it must transmit its current status to the GCS, and the GCS controls the UAV maneuvers by transmitting control packets to it.…”
