Digital Twin-enabled 6G Aerial Edge Computing with Ultra-Reliable and Low-Latency Communications : (Invited Paper)

Abstract

In this paper, we deal with an end-to-end (e2e) latency minimisation problem of digital twin-aided offloading in edge networks with the support of unmanned aerial vehicle (UAV) employed by multiple antennas under the stringent constraints of ultra-reliable low-latency communications (URLLC) links. The minimised latency is obtained by jointly optimising the transmit power, offloading factors, and the processing rate of Internet of Things (IoT) devices and edge servers (ES). An alternative optimisation approach combined with appropriate inner approximations is effectively exploited to tackle this challenging problem. Numerical results of various simulations are presented to validate the proposed digital twin solution to support IoT applications.
