The architecture can deliver two streams of information, namely: aerial images and HD videos by UAVs, and audio-visual contents from ground WSN. Additionally, SkyMedia can support reality maps that offer a bird's eye view to event information. However, limited converge footprint is reported as an open issue. Researchers in [19] have highlighted coupling social media and drone sensing for re-liable disaster response applications via developing a reliable social signal distillation module to evaluate the event truthfulness and the source reliability. Results emphasize that a drone is an effective solution in providing disaster response for journalists' missions. The work in [20] presents an integrated AI and UAV framework based on a scheduling solution using the Reinforcement Machine Learning technique to increase quality for live video streaming in short-term, large-scale events (e.g., sport events). The framework discusses three main scheduling solutions which are: Static Prioritization (SP), Required Activity Detection Scheduler (RADS), and Frame Level Scheduler (FLS). The proposed scheduling solution gives reasonable results in terms of Peak Signal-to-Noise Ratio (PSNR), throughput, and packet loss rate. However, no consideration has been taken from air-to-ground link budget parameters; most importantly path loss (PL) and Received Signal Strength (RSS), where these are two main performance indicators for any wireless communication systems. Therefore, this was a motivation in our paper. UAVs are either autonomous or remotely piloted aircrafts without requiring a human on board to fly, that can be fitted with cameras, sensors, and telecommunication payloads, to collect many types of digital, visual, and environmental data. UAVs can be classified by a broad number of characteristics such as shape, weight, endurance, range, speed, and wing loading. Further, UAVs can be divided generally into two types: aircrafts and airships. The aircrafts include fixed-wing aircraft, self-guided aircraft, or remotely piloted aircraft (e.g., drones). The airships include High/Low Altitude Platforms (HAPs or LAPs), FloatingBalloons, or Tethered Balloons. UAVs have drawn expectedly tremendous attention due to their advantages and wide applications including wireless telecommunications, monitoring, high-resolution imaging, empowering smart cities, smart agriculture, atmospheric studies, remote sensing, localization, and navigation [21; 22; 23]. An individual drone or a set of drones have been implemented in [24] to mediate real-time breaking news coverage and to support the future drone journalism services. The study emphasized that drones have merits of the smart journalism concept including a longer range, and fast news gathering and broadcasting that can be done using an autonomous drone. Researchers in [25] shed the light on key advantages of using UAVs by journalists' news organizations including short time of gathering news, wide angle of coverage, and offering media content from disaster areas that are inaccessible by journalists. The article also highlights rules and regulations that are set by international bodies such as the Federal Aviation Administration (FAA) and how these are shaping the use of UAVs for journalism. Using drones or even any form of UAVs' platforms for media and journalism would need a wireless link budget that should be optimized. Thus, many researchers have been striving to provide various solutions in optimizing a link budget, which in turn leads to enhance wireless connectivity and throughput. These merits can be translated in a media and journalism context as high capacity of livestreaming, HD aerial imaging, and rapid and flexible news gathering. The drone technology is realized as an added value to wireless communications and to widen smart applications. Moreover, drones can be accomplished with many wireless services that can be provided from space layer to terrestrial fixed, and/or mobile users.
