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.

I. Introduction

Drones have become promising in real life and military applications with the extensive technological advances in their research. The research on flying ad hoc networks (FANETs) so far focused heavily on optimal routing algorithms and path planning of drone swarm networks. Despite the fact that link disconnections occur frequently among the drones because of the high speed of drones and rapidly changing environment, no studies focused on the network connectivity between drones [1].
