A Study on the Flying Ad-hoc Networks: Related Challenges, Routing Protocols and Mobility Models

Unmanned aerial vehicle (UAV) systems have gained extensive attention as open up new possibilities for special forces and military observations. However, research challenges and new solutions for the operation of UAVs need to be understood in better way so as develop adaptable and adjustable UAVs. In present piece of review, we report advantages of multiple UAV systems, classification of various types of Ad-Hoc networks, challenges in Ad-Hoc networks, routing protocols of Flying Ad-Hoc Network (FANET), and mobility models of FANETS. The review mainly focusses on important FANET design concerns. Moreover, comparison of FANET Ad-Hoc network has been made with Vehicular Ad-Hoc network as well as Mobile Ad-Hoc network in terms of speed, density and energy consumption etc. The information provided in this review will help the reader to understand the intricacies of UAV systems.
