Multiple CUAV-Enabled mMTC and URLLC Services: Review of Energy Efficiency and Latency Performance

Abstract

<p>Cognitive unmanned aerial vehicles (CUAVs) play a vital role in next-generation wireless networks as they assist in massive machine-type communication (mMTC) and ultra-reliable low-latency communication (URLLC) services. This study focuses on multiple CUAV-enabled networks, wherein CUAVs are paired with each other. We analyze the data rate, energy efficiency, and latency of such networks by applying the finite information block length theory, wherein mMTC and URLLC information use a non-orthogonal multiple access technique. Furthermore, we formulate an optimization problem to maximize the energy efficiency of paired CUAV devices by jointly optimizing the transmission power of the mMTC and URLLC information to satisfy the latency requirement. The numerical results indicate that our proposed multiple-CUAV-enabled scheme enhances the network performance of CUAV devices in terms of energy efficiency and latency better than the existing scheme.</p>

“…UAVs playing a crucial role in providing rapid connectivity in areas with poor communication [169]. In addition to their mobility and small size, UAVs can also be used for establishing ad hoc networks in remote locations like deserts and mountains where traditional communication methods may not be readily available.…”
