Autonomous Delivery of Multiple Packages Using Single Drone in Urban Airspace

Examples of these applications include public security, remote sensing, surveillance, photography, and delivery of goods [2]. The continual growth of e-commerce, especially during the COVID-19 pandemic, has revolutionized the way customers acquire goods and services [3]. The ubiquity of drones in the sky has prompted an increasing interest of several e-commerce companies such as UPS, Flytrex, and Amazon Prime Air to use drones for package delivery [4]. Several countries have used drones for safe and contactless deliveries during the pandemic lockdowns [5]. Drone delivery is highly desired in urban areas to reduce delivery time and traffic congestion on roads by utilizing urban airspace [6]. The recent developments in drone technology show that drones can carry multiple packages [7]. Therefore, a drone can serve more than one customer in one trip.
