Nowadays, Unmanned Aerial Vehicles (UAVs) are being used in several novel\napplications, especially in the telecommunication domain. However, ensuring UAV\ncommunication and networking for the purpose of a specific application is still\nchallenging. Indeed, due to the mobility of a UAV in a vast area, permanent\nconnectivity over the back-haul is very sporadic and might be lost. In this\npaper, we consider an aerial mesh network where each UAV can serve as a flying\nbase station to boost terrestrial base station in case of damaged\ninfrastructure case for example, or/and provide connectivity for uncovered or\npoorly covered nodes, and behaves as a relay to establish communication between\ntwo components owing to a lack of reliable direct communication link between\nthem. We then detail a case study where a UAV-fleet are used to collect data\nfrom the ground Internet of Things (IoT) devices and forward it to cloud for\nfurther processing passing by a remote gateway.\n We aim here to build a queueing framework including network layer, MAC layer,\nand physical layer and investigate both uplink and downlink communication\nlinks. Next, we derive some closed forms allowing us to predict the network\nperformance in terms of traffic intensity at every UAV of the aerial mesh\nnetwork, end-to-end (E2E) throughput and e2e delay of ongoing streams. Next, we\nconduct extensive simulations to illustrate the benefit of our framework.\nResults discussion and numerous insights on parameter setting, target quality\nof service and design consideration are also drawn.\n
