An UAV-assisted VANET architecture for intelligent transportation system in smart cities

Vehicular ad hoc network is a pretty research vibrant area since last decade. It has been successfully used for intelligent transportation system and entertainment purposes realization of smart cities. However, intermittent connectivity, high routing overhead, inflexible communication infrastructure, unscalable networks, packet collision are the key challenges that put hindrances on wide applications vehicular network. The severity these become even more intensified when deployed in urban areas. To overcome hurdles, integrating micro unmanned aerial vehicles with provides viable solution. In this article, we proposed an vehicle–assisted architecture which fly over provide services to underlying coverage area. Unmanned avails advantages line-of-sight communication, load balancing, flexible, cost effective deployment. performance model evaluated against case study vehicle highway. Results show utilization ensures guaranteed timely delivery emergency messages nearby so safe action can be taken avoid further damages.
