Kawalan Akses Media (MAC) adalah penting untuk menjamin keperluan Kualiti Perkhidmatan (QoS) yang berbeza untuk rangkaian Kenderaan Udara Tanpa Pemandu (UAV), seperti kebolehpercayaan yang tinggi untuk paket keselamatan dan pemprosesan tinggi untuk paket perkhidmatan. Sementara itu, disebabkan keupayaan mereka untuk memberikan kelewatan yang lebih rendah dan kadar data yang lebih tinggi, lebih banyak UAV menggunakan antena yang kerap berarah. Walau bagaimanapun, adalah mencabar untuk menyokong QoS yang berbeza dalam rangkaian UAV dengan antena berarah, kerana mobiliti UAV yang tinggi yang menyebabkan kehilangan sumber saluran yang serius. Dalam kertas ini, kami mencadangkan CU-MAC yang merupakan protokol MAC untuk rangkaian UAV Berpusat dengan antena arah. Pertama, kami mereka bentuk skim pengoptimuman rangka masa berdasarkan ramalan mobiliti untuk menyediakan perkhidmatan penyiaran yang boleh dipercayai untuk paket keselamatan. Kemudian, skim peruntukan saluran berasaskan ramalan trafik dicadangkan untuk menjamin keutamaan paket video yang merupakan paket perkhidmatan yang paling biasa pada masa kini. Keputusan simulasi menunjukkan bahawa berbanding dengan protokol perwakilan lain, CU-MAC mencapai kebolehpercayaan yang lebih tinggi untuk paket keselamatan dan meningkatkan daya pemprosesan paket perkhidmatan, terutamanya paket video.

Abstract: Media Access Control (MAC) is critical to guarantee different Quality of Service (QoS) requirements for Unmanned Aerial Vehicle (UAV) networks, such as high reliability for safety packets and high throughput for service packets. Meanwhile, due to their ability to provide lower delay and higher data rates, more UAVs are using frequently directional antennas. However, it is challenging to support different QoS in UAV networks with directional antennas, because of the high mobility of UAV which causes serious channel resource loss. In this paper, we propose CU-MAC which is a MAC protocol for Centralized UAV networks with directional antennas. First, we design a mobility prediction based time-frame optimization scheme to provide reliable broadcast service for safety packets. Then, a traffic prediction based channel allocation scheme is proposed to guarantee the priority of video packets which are the most common service packets nowadays. Simulation results show that compared with other representative protocols, CU-MAC achieves higher reliability for safety packets and improves the throughput of service packets, especially video packets.
