This decade sees a growing number of applications
of Unmanned Aerial Vehicles (UAVs) or drones. UAVs are now
being experimented for commercial applications in public areas
as well as used in private environments such as in farming. As
such, the development of efficient communication protocols for
UAVs is of much interest. This paper compares and contrasts
recent communication protocols of UAVs with that of Vehicular
Ad Hoc Networks (VANETs) using Wireless Access in Vehicular
Environments (WAVE) protocol stack as the reference model.
The paper also identifies the importance of developing lightweight
communication protocols for certain applications of UAVs
as they can be both of low processing power and limited battery
energy.
