Reliable and flexible emergency communication is a key challenge for search and rescue in the event of disasters, especially for the case when base stations (BSs) are no longer functioning. Unmanned aerial vehicle (UAV) assisted network is emerging as a promising method to establish emergency networks. In this article, a unified framework of UAV-assisted emergency network is established in disasters. First, the trajectory and scheduling of UAV are jointly optimized to provide wireless service to ground devices with surviving BSs. Then, the transceiver design of UAV and establishment of multi-hop ground device-todevice (D2D) communication are studied to extend the wireless coverage of UAV. In addition, multi-hop UAV relaying is added to realize information exchange between the disaster areas and outside through optimizing the hovering positions of UAVs. Simulation results are presented to show the effectiveness of these three schemes. Finally, open research issues and challenges are discussed.

“…Message wireless transmission systems with the assistance of UAVs in large-scale disasters were studied by Mase and Okada in [14]. UAV flying path was optimized by Christy et al for D2D communication in disasters in [15]. A systematic study of UAV-assisted emergency networks is missing in the literature.…”

“…Moreover, a deployment approach based on the combination of global and local search was exploited by Reina et al, to achieve optimal positioning of UAVs in disasters [23]. Meanwhile, in [24], UAV flying paths that can adapt to disaster condition and satisfy the energy constraint simultaneously were presented by Christy et al Although there are some advantages of using UAVs as flying BSs, many technical challenges still exist, including interference management, energy constraint and coverage limitation, etc. In particular, the disaster area may be very large, but the wireless coverage of UAV is limited due to insufficient battery.…”

On the Outage Probability and Power Control of D2D Underlaying NOMA UAV-Assisted Networks

Unmanned aerial vehicle (UAV) nowadays is a promising technology for boosting wireless connectivity, especially for upcoming 5G wireless networks. Due to its aerial feature, potential mobility and flexible deployment, the UAV can provide service in some specific scenarios such as post-disaster network recovery or no-infrastructure terrains. However, the problem of interference management between deployed UAV and underlaying heterogeneous networks, which guarantees the quality of service, is still a challenging task. In this paper, we address the outage probability for UAV connected users and device-to-device (D2D) receivers simultaneously operating in D2D underlaying NOMA UAV-assisted networks, and we derive its closed-form expressions, which turns out to be very accurate. We also solve the power control optimization problem via relaxing the non-convex problem into solving successive low-complexity linear programs to obtain a sub-optimal solution to the problem. The simulation results in confirm the superiority of the proposed approach in the terms of computational complexity and its compromise in the terms of sum rate.
