Self-Recovery Scheme Using Neighbor Information for Multi-drone Ad Hoc Networks

Drones have various applications, such as rescue and exploration in disaster situations, surveillance in military, monitoring and management of crops in agriculture field. For such a wide variety of applications, a multi-drone system using several drones can further improve the efficiency of the tasks. In addition, the multi-hop communication using multiple drones can enhance the radius of operation. In multi-drone systems, it is important to establish a stable network between the drone and controller. This paper focuses on the fast network recovery in multi-drone ad hoc network environments. We compare the proposed scheme with the network non-recovery environment, and confirm that the proposed scheme outperforms the network non-recovery scheme in terms of the packet delivery ratio and the average network disconnection time.
