“…[6][7][8] By using these models, we need no prior information about exact number and location of ABSs, and hence, we can use stochastic geometry in ABSs and model them randomly in space. [9][10][11][12][13] In other words, at the beginning step of network design, we find the efficient density of ABSs, and hence, we can easily obtain the relationship between network parameters and its performance. 9,11 After this step, we know some details about the network parameters and the relationships between them.…”

In this paper, we propose a new scheme called dynamic power‐dynamic density at which our goal is to maximize the throughput of aerial base station–based networks with coverage probability and power density constraints. The corresponding optimization problem is nonconvex and intractable. To tackle this issue, we propose an iterative algorithm based on the well‐known alternative method. In this method, we decompose the optimization problem into two nonconvex subproblems, namely, power allocation and density finding. Then, in order to provide a low complex and high speed algorithm, these subproblems are transformed into geometric programming forms, which can be solved by existing convex tools. Moreover, the convergence of the proposed iterative scheme is proved and it is studied from the computational complexity perspective. To investigate the performance of the proposed algorithm with existing schemes, we consider two other schemes, namely, dynamic power‐fixed density and dynamic density‐fixed power. Based on simulation results, the throughput of aerial base stations in our scheme is approximately 27% more than that of the two existing schemes. Furthermore, the trade‐off between power and density for different network parameters is studied.

“…The adoption of UAV-mounted access points has been widely examined for use in wireless sensor networks [5], [6], [7], with the telecom community beginning to consider similar technology in commercial cellular networks [8], [9], [10], [11]. In [9] the authors demonstrate in real-life trials that an access point mounted on a UAV is capable of acting as a relay for UEs in an urban environment. In [8], [11] the authors consider UAVs as backups in macrocell networks in the event of BS outage, with the UAVs being used to plug coverage holes that arise from a BS going offline.…”

Abstract-We envision small cells mounted on unmanned aerial vehicles, to complement existing macrocell infrastructure. We demonstrate through numerical analysis that clustering algorithms can be used to position the airborne access points and select users to offload from the macrocells. We compare the performance of these deployments against equivalent simulated picocell deployments. We demonstrate that due to their ability to position themselves around exact user locations while maintaining a direct line-of-sight link the airborne access points provide a significantly improved received signal strength than the static picocell alternatives. We also find that the airborne access points provide superior service quality even in the presence of user and access point positioning errors.

In the development of beyond-line-of-sight (BLOS) Unmanned Aerial Vehicle (UAV) systems, communication between the UAVs and the ground control station (GCS) is of critical importance. The commonly used economical wireless modules are restricted by the short communication range and are easily blocked by obstacles. The use of a communication relay system provides a practical way to solve these problems, improving the performance of UAV communication in BLOS and cross-obstacle operations. In this study, a communication relay system, in which a quadrotor was used to relay radio communication for another quadrotor was developed and tested. First, the UAVs used as the airborne platform were constructed, and the hardware for the communication relay system was selected and built up. Second, a set of software programs and protocol for autonomous mission control, communication relay control, and ground control were developed. Finally, the system was fully integrated into the airborne platform and tested both indoor and in-flight. The Received Signal Strength Indication (RSSI) and noise value in two typical application scenarios were recorded. The test results demonstrated the ability of this system to extend the communication range and build communication over obstacles. This system also shows the feasibility to coordinate multiple UAVs’ communication with the same relay structure.
