Prof. Kamesh Namuduri

Kamesh Namuduri is a Professor of Electrical Engineering and the director of Autonomous Systems Laboratory at the University of North Texas (UNT). He received his B.S. degree in Electronics and Communication Engineering from Osmania University, India, in 1984, M.S. degree in Computer Science from University of Hyderabad in 1986, and Ph.D. degree in Computer Science and Engineering from University of South Florida in 1992. Over the past eleven years, his research is focused on aerial networking and communications. He co- organized a series of workshops on “Airborne Networking and Communications” in conjunction with IEEE, AIAA, AUVSI, and ACM Conferences. He is serving as the chair for two Standards Working Groups (IEEE 1920.1: Aerial Communications and Networking and IEEE P1920.2: Vehicle-to-Vehicle Communications for Unmanned Aircraft Systems). He is serving as the Chair for the IEEE Vehicular Technology Society’s Ad Hoc Committee on Drones. He is a co-editor for the book titled “UAV Networks and Communications” published by the Cambridge University Press in 2017. He is leading the Smart and Connected Community project on “Deployable Communication Systems” in collaboration with the government, public, and private organizations. This living laboratory project was demonstrated thrice during the Global City Teams Challenge hosted jointly by the National Institute of Standards and Technology and US Ignite in 2015, 2016, 2017, and 2018. He contributed to the development of research agenda, requirements and blueprints highly deployable communications systems led by the National Institute of Standards and Technology and National Public Safety Telecommunications Council.
A Vehicle-to-vehicle (V2V) communication system provides a means for direct communication between two aircraft systems. If every vehicle is equipped with a V2V system then V2V can be extended to create an ad hoc network of multiple unmanned aircraft systems (UASs). In general, V2V is useful for real-time information sharing between the aircraft. In the context of UAS Traffic Management (UTM), there are two primary benefits of V2V communications: 1. Collision Avoidance and 2. Beyond Radio Line of Sight (BRLoS) communications. In conjunction with Remote ID, V2V communications play an important role in UAS Traffic management. A V2V communication system allows for direct communication between two aircraft and more generally among multiple aircraft. This communication primarily consists of aircraft identification, telemetry information including current Global Positioning System (GPS) coordinates, heading, acceleration, distress status, at the very least. Sharing telemetry information between aircraft allows for implementation of collision avoidance strategies in the airspace. As each UAS receives telemetry information from its neighbors, it can determine potential conflicts that may arise, and avoid such conflicts by implementing established deconfliction strategies. A deconfliction strategy may also consider telemetry and other relevant information received from the other aircraft such as the battery status, distress level (if any) that could affect the aircraft’s mobility. A predetermined algorithm would then estimate the best course of deconfliction while taking the surrounding environment into account as well, avoiding any additional obstacles that may be present, to allow the aircraft to continue on its revised flight plan. Another use of V2V system would be relaying or forwarding telemetry packets that an aircraft receives from its neighbors to a Ground Control Station (GCS) while they are out of communication range.
This presentation is based on the UAS-to-UAS Communication trials that were conducted as part of the UTM Technology Capability Level 4 flight tests by the Lone Star Center of Excellence and Innovation, Texas A&M University, under the supervision of National Aeronautics and Space Administration, in Corpus Christ, Texas, during the summer 2019.
