Unmanned Aerial System Traffic Management with WAVE Protocol for Collision Avoidance

Abstract

Recently, the number of drones for personal leisure as well as Unmanned Aerial Vehicles (UAVs) for such as military, commercial, agricultural, disaster response is increasing rapidly. When a large number of UAVs fly simultaneously in airspace, collision problems between UAVs can occur, which is likely to lead directly to human accidents or economic loss. Accordingly, there are growing needs for UAS Traffic Management (UTM) systems. In this phenomenon, various communication protocols for UTM are emerging. In this paper, especially, the application of UTM system based on Wireless Access in Vehicular Environment (WAVE) protocol is introduced as one of most efficient and stable protocols in environments with high-speed mobility and dynamic changing topology. Furthermore, we design a network architecture that supports direct communication among UAVs as well as UAV and ground station within the UTM framework. By applying WAVE protocol in the UTM system, it is possible to transmit messages promptly and accurately to prevent collision in the event of an emergency, and to configure the UTM system to manage all UAVs by applying a WAVE-based ad-hoc network.
