Review on the Hybrid-Electric Propulsion System and Renewables and Energy Storage for Unmanned Aerial Vehicles

open access: yesInternational Journal of Electrochemical Science, 2020
The unmanned aerial vehicle (UAV) is an aircraft without a human pilot, and thus the primary applications of UAVs are surveillance without human loss. A low altitude surveillance aircraft is the foundation for the use of light sensor payloads in a small ...

A predefined channel coefficients library for vehicle-to-vehicle communications [PDF]

open access: yes, 2015
It is noticeable that most of VANETs communications tests are assessed through simulation. In a majority of simulation results, the physical layer is often affected by an apparent lack of realism.

Connectivity Analysis in Vehicular Ad-hoc Network based on VDTN

open access: yesJournal of Communications Software and Systems, 2023
In the last decade, user demand has been increasing exponentially based on modern communication systems. One of these new technologies is known as mobile ad-hoc networking (MANET). One part of MANET is called a vehicular ad-hoc network (VANET).

Poster Abstract: Hierarchical Subchannel Allocation for Mode-3 Vehicle-to-Vehicle Sidelink Communications [PDF]

open access: yes, 2017
In V2V Mode-3, eNodeBs assign subchannels to vehicles in order for them to periodically broadcast CAM messages \cite{b2}. A crucial aspect is to ensure that vehicles in the same cluster will broadcast in orthogonal time subchannels\footnote{A subchannel ...
