Special Issue Information

Dear Colleagues,

UAV (Unmanned Aerial Vehicle)-assisted mobile wireless networks are expected to be used in a wide range of applications such as agriculture, transport, environmental monitoring and rescue operations. To realize these applications, it is crucial to establish efficient network operation techniques. Therefore, the special issue calls for papers regarding the recent advances related to UAV-assisted mobile wireless networks in a wide range of topics, including (but not limited to) the following:

  • UAV mobile control techniques
  • Control of UAV-assited networks
  • Performance evaluation of UAV-assited networks
  • Applications for UAV-assisted mobile wireless networks
  • Multi-hop networking
  • Traffic management in UAV-assisted networks
  • Smart autonomous networks
  • UAV sensor networks
  • Security meassures for UAV networks
  • Energy-efficient routing
  • On-UAV edge computing
  • Collision avoidance for UAVs
  • Experimental platforms for UAV-aided mobile networks
  • AI-based UAV network control

Networks constructed in the sky are known as non-terrestrial networks (NTNs). As an example of an NTN, relay transmission using drones as radio stations enables flexible network construction in the air by performing handovers with ground stations. However, the presence of structures or obstacles in the flight path causes multipath interference; consequently, the propagation environment fluctuates significantly based on the flight. In such a communication environment, it is difficult for a drone to select an optimal ground station for a handover. Moreover, unlike a terrestrial network, the propagation environment of a flying drone is affected by structures and other factors that cause multipaths based on the flight speed and altitude, making the conditions of the propagation environment even more complex. To solve these problems, we propose handover schemes between drones and the ground that consider the multipath interference caused by obstacles. The proposed methods are used to perform handovers based on an optimal threshold of received power considering interference and avoid unnecessary handovers based on the moving speed, which makes the handover seamless. Finally, we develop a simulator that evaluates the cross layer from propagation to upper network protocols in a virtual space, including buildings, evaluate the communication quality of a drone flying in a three-dimensional space, and confirm the effectiveness of the proposed methods as well as the evaluation of the real environment.

In this paper, we delve into the domain of heterogeneous drone-enabled aerial base stations, each equipped with varying transmit powers, serving as downlink wireless providers for ground users. A central challenge lies in strategically selecting and deploying a subset from the available drone base stations (DBSs) to meet the downlink data rate requirements while minimizing the overall power consumption. To tackle this, we formulate an optimization problem to identify the optimal subset of DBSs, ensuring wireless coverage with an acceptable transmission rate in the downlink path. Moreover, we determine their 3D positions for power consumption optimization. Assuming DBSs operate within the same frequency band, we introduce an innovative, computationally efficient beamforming method to mitigate intercell interference in the downlink. We propose a Kalai–Smorodinsky bargaining solution to establish the optimal beamforming strategy, compensating for interference-related impairments. Our simulation results underscore the efficacy of our solution and offer valuable insights into the performance intricacies of heterogeneous drone-based small-cell networks. Full article
