Unmanned aerial vehicle: a review and future directions

The use of unmanned aerial vehicles (UAVs) will be crucial in the next generation wireless communications infrastructure. When compared to traditional ground-based solutions, it is expected that their a variety communication-based applications increase coverage and spectrum efficiency. In this paper, we provide detailed review all relevant research works as follows. This paper presents types UAVs (e.g., coverage, military, agriculture, medical applications, environment, climate, delivery transportation), characteristics node density, altering system topology, mobility, radio broadcasting mode, frequency band, localization, power consumption network lifetime), application Multi-UAV cooperation, UAV-to-VANET collaborations, UAV-to-ground tasks). Additionally, reviews routing protocols topology-based, position-based, heterogeneous, delay-tolerant networks (DTNs), swarm-Based, cluster-based) simulation tools OMNeT++, AVENS, MATLAB, NS3, SUMO, OPNET). design development any new methods for may work guide reference.
