V2V UAS communications and use cases for advanced air mobility

Abstract

Advanced Air Mobility (AAM) is emerging as a transformative application in smart mobility with the latest advances in hardware, software, policy development, and regulations. Unmanned Aircraft Systems (UAS) are supposed to become the backbone of emerging AAM services and applications as connected and software-intensive platforms. However, Vehicle-to-Vehicle (V2V) communications in the AAM still deserve further effort in terms of safety, communication protocols, data exchange requirements, concrete use cases and their subsequent standardization. To this end, this paper presents several use cases for UAS communications and relevant message exchange protocols currently investigated in IEEE P1920.2 Standardization Work Group. The use case constellation entails five fundamental use cases for V2V UAS communications in the AAM domain. This paper begins with an overview of these use cases for potential scenarios. Then, it further delves into two critical ones and describes the relevant data exchange and protocol flows for UAS communications. We believe that this contribution will facilitate the discussion of AAM use cases and crucial aspects of V2V communications employed in these scenarios.
