To examine whether deploying airborne unmanned aerial vehicles as communication relays can mend broken links and reduce data delivery delays in sparse vehicular networks.
Formulated a UAV mobility model to analytically capture macroscopic dynamics of drones operating under waypoint mobility along a roadway segment.
Developed a stochastic analytical model to mathematically evaluate end-to-end data delivery delay and path availability across ground and aerial entities.
Built a simulation framework to validate the analytical models and assess connectivity gains in free-flow vehicular traffic.
The stochastic formulation accurately characterizes dynamic path availability and transmission latency fluctuations caused by free-flow vehicular dynamics.
Simulation findings confirm that integrating drone-based aerial relays strengthens intermittent communication links and lowers data delivery delays between vehicles and roadside units.
