Connecting flying backhauls of unmanned aerial vehicles to enhance vehicular networks with fixed 5G NR infrastructure

This paper investigates moving networks of Unmanned Aerial Vehicles to extend connectivity and guarantee data rates in the 5G by analysing possible hovering locations based on limitations such as flight time coverage. The authors provide analytic bounds requirements terms extension for vehicular served fixed Enhanced Mobile BroadBand infrastructure, where both infrastructures are modelled using stochastic fractal geometry a model urban environment. prove that assuming n mobile nodes (distributed according hyperfractal distribution dimension dF) an average ρ Next Generation NodeB (gNBs), distributed like dr if = nθ with θ > dr/4 letting tending infinity (to reflect megalopolis cities), then fraction not covered gNB tends zero O − d F 2 r $O\left({n}^{-\frac{\left({d}_{F}-2\right)}{{d}_{r}}\left(2\theta -\frac{{d}_{r}}{2}\right)}\right)$ . Interestingly, number drones, needed connect each node gNBs, is comparable isolated nodes. complete characterisation proving when < proportion zero. offer insights placement ‘garage drones’, home location these nomadic infrastructure nodes, minimise ‘flight-to-coverage time’. fast procedure select relays will be garages (and store drones) order delay. authors’ analytical results confirmed simulations Matlab.
