“…As a single metric, energy efficiency (EE) characterizes the amount of successfully transmitted bits per unit energy. In [11]- [13], energy-efficient terrestrial half-duplex relaying (HDR) transmissions were investigated, where the transmitting power was optimized. To effectively improve the energy efficiency for slotted transmission, the optimal slot length maximizing the energy efficiency is investigated in [13].…”

In this paper, an energy-efficient full-duplex (FD) unmanned aerial vehicle (UAV) relaying network is proposed, where UAV acts as a mobile relay and assists information exchange between two transceivers. Specifically, the load-carry-and-delivery scheme is applied to positively take advantage of the time-varying channel gain in delay-tolerant networks; meanwhile, the FD communication policy is used to potentially further increase the energy efficiency (EE). In particular, the self-interference channel gains follow the complex Gaussian distribution instead of being constant. The EE is first rigorously derived and then, the optimum flight speed is determined under the information causality constraint to maximize the EE. Numerical results demonstrate that the proposed scheme outperforms the half-duplex as well as static schemes in terms of the EE. In addition, the impact of the self-interference cancellation factor on the EE is also demonstrated, which provides valuable insights for the system design of UAV-assisted relaying networks.INDEX TERMS Energy efficiency (EE), delay-tolerant networks, full-duplex relaying (FDR), load-carryand-delivery (LCAD), UAV.

“…Therefore, energy efficiency (EE), which is measured as the number of successfully transmitted bits per unit energy, has become a key performance indicator. In [13][14][15] energy-efficient terrestrial half-duplex relaying (HDR) transmissions were investigated and transmission power was optimized. The EE maximization problem for slotted transmissions was investigated in [15].…”

As an emerging technology, unmanned aerial vehicles (UAVs) are being developed for various applications, including UAVassisted smart city architectures, agriculture, and industrial development [1]. In particular, UAV-integrated communications have attracted significant research attention [1,2] (and the references therein), particularly for urgent or dangerous communication scenarios (eg, border detection and remote sensing). Such applications are facilitated by the low cost, deployment flexibility, and full controllability in 3D airspaces of UAVs. Compared to terrestrial systems, UAV wireless systems offer several advantages, including superior link quality for communication channels [3] and greater link connection
