摘要

In this work, we analyze the effect of relaying network where unmanned aerial vehicles (UAVs) act as cache-aided relay nodes. Unmanned aerial vehicle (UAV) has high mobility, which can be flexibly scheduled when unable to communicate so that it can act as a wireless relay to assist communication. It can provide a more flexible deployment mode in different application scenarios to improve the performance of communication. What is more, how to transform the dynamic characteristics of UAVs into channel characteristics is also a challenge. To be more specific, UAVs act as decoded-and-forward (DF) relays to assist the wireless communication between the source and destination, and the speed and flying height remains unchanged. The UAVs are equipped with a wireless cache, which can provide reliable services and expand the channel capacity to reduce the outage probability of the network. Experimental and simulation results verify the effect of UAVs with cache on the outage performance in relaying networks. (C) 2021 Published by Elsevier B.V.
