Dans cet article, on considère un réseau de communication sans fil qui utilise des véhicules aériens sans pilote (UAV) dans le ciel pour transmettre des informations entre utilisateurs au sol. Nous mettons en évidence un réseau tolérant aux délais, dans lequel les informations sont relayées de manière stockée et retransmise en établissant deux types de liens de communication intermittents : entre un drone et un utilisateur (UAV à utilisateur) et entre des drones (UAV à utilisateur). drone). Ainsi, un algorithme de vol contrôlant le mouvement des drones est crucial pour parvenir à une transmission rapide des informations. Notre étude propose de nouveaux algorithmes de vol qui considèrent simultanément les deux types de liens de communication. Dans les liaisons UAV-UAV, la transmission directe d’informations entre deux UAV et la transmission indirecte via d’autres UAV sont considérées séparément. Le mouvement des drones est contrôlé en résolvant un problème d'optimisation à certains intervalles de temps, avec un rapport de considération variable des deux types de liaisons. De plus, nous étudions non seulement le cas où tous les drones se déplacent de manière coopérative, mais également le cas où chaque drone se déplace de manière autonome. Les résultats de simulation montrent que les algorithmes proposés sont efficaces. De plus, ils indiquent l'existence d'un rapport de considération optimal des deux types de communication et démontrent que notre approche permet de contrôler les fréquences d'établissement des liens de communication. Nous concluons que l’augmentation de la fréquence des communications indirectes entre les drones améliore les performances du réseau.

Abstract: In this paper, a wireless communication network that uses unmanned aerial vehicles (UAVs) in the sky to transmit information between ground users is considered. We highlight a delay-tolerant network, where information is relayed in a store-and-forward fashion by establishing two types of intermittent communication links: between a UAV and a user (UAV-to-user) and between UAVs (UAV-to-UAV). Thus, a flight algorithm that controls the movement of the UAVs is crucial in achieving rapid information transmission. Our study proposes new flight algorithms that simultaneously consider the two types of communication links. In UAV-to-UAV links, the direct information transmission between two UAVs and the indirect transmission through other UAVs are considered separately. The movement of the UAVs is controlled by solving an optimization problem at certain time intervals, with a variable consideration ratio of the two types of links. In addition, we investigate not only the case where all UAVs move cooperatively but also the case where each UAV moves autonomously. Simulation results show that the proposed algorithms are effective. Moreover, they indicate the existence of an optimal consideration ratio of the two types of communication and demonstrate that our approach enables the control of frequencies of establishing the communication links. We conclude that increasing the frequency of indirect communication between UAVs improves network performance.
