Dalam makalah ini, rangkaian komunikasi tanpa wayar yang menggunakan kenderaan udara tanpa pemandu (UAV) di langit untuk menghantar maklumat antara pengguna darat dipertimbangkan. Kami menyerlahkan rangkaian bertolak ansur kelewatan, di mana maklumat disampaikan secara menyimpan dan ke hadapan dengan mewujudkan dua jenis pautan komunikasi terputus-putus: antara UAV dan pengguna (UAV-ke-pengguna) dan antara UAV (UAV-ke- UAV). Oleh itu, algoritma penerbangan yang mengawal pergerakan UAV adalah penting dalam mencapai penghantaran maklumat yang pantas. Kajian kami mencadangkan algoritma penerbangan baharu yang mempertimbangkan kedua-dua jenis pautan komunikasi secara serentak. Dalam pautan UAV-ke-UAV, penghantaran maklumat langsung antara dua UAV dan penghantaran tidak langsung melalui UAV lain dianggap secara berasingan. Pergerakan UAV dikawal dengan menyelesaikan masalah pengoptimuman pada selang masa tertentu, dengan nisbah pertimbangan berubah bagi dua jenis pautan. Selain itu, kami menyiasat bukan sahaja kes di mana semua UAV bergerak secara kooperatif tetapi juga kes di mana setiap UAV bergerak secara autonomi. Keputusan simulasi menunjukkan bahawa algoritma yang dicadangkan adalah berkesan. Selain itu, ia menunjukkan kewujudan nisbah pertimbangan optimum bagi kedua-dua jenis komunikasi dan menunjukkan bahawa pendekatan kami membolehkan kawalan frekuensi mewujudkan pautan komunikasi. Kami menyimpulkan bahawa meningkatkan kekerapan komunikasi tidak langsung antara UAV meningkatkan prestasi rangkaian.

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.

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).

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.
