Participation of MONUSEN’s researchers at the conference IT 2024

The MONUSEN’s research team members from Montenegro have participated in the Conference on Information Technology 2024 held from the 21^st to the 24^th of February 2024 in Žabljak. The researchers Luka Martinović, MSc and Prof. Žarko Zečević presented the paper titled “KF-based LOS Guidance Law for Path Following of USV: Experiments and Performance Evaluation.” This paper showcases the experimental results of the guidance algorithm for straight-line following of marine vehicles, developed in collaboration with partners from CNR as part of the MONUSEN project. Experiments on a real vehicle were conducted in Genoa during the two-month stay of Luka Martinović, MSc and Prof. Žarko Zečević at CNR. 

Luka Lazović, PhD presented a paper titled “Implementation of Chaotic DSSS Technique for Underwater Acoustic Communication System,” authored by Luka Lazović, Jeffrey Neasham, Benjamin Sherlock, Ana Jovanović, and Vesna Rubežić. The investigation presented in the poster section represents a continuation of research and development in underwater acoustic communication initiated during Luka Lazovićs short exchange program at the University of Newcastle as part of the MONUSEN project. The primary objective of this research is to enhance the low data rate, which constitutes the main limitation of the previously developed DCSK modulation system. Conducting research in this domain, particularly under real-world conditions, presents significant challenges owing to the diverse underwater communication channels, various human activities, and microclimatic factors prevalent in the specific area. The proposed methodology involves the application of the Chaotic Direct-Sequence Spread Spectrum (DSSS) Technique for an Underwater Acoustic Communication System. A Lorenz chaotic map serves as the spreading sequence generator for the Direct-Sequence Spread Spectrum.

During the same conference, master’s students in control engineering, Vladimir Ćetković and Mitar Otašević, presented papers “Improved LOS Guidance Law for Curved Path Following of Underactuated USV in Presence of Ocean Currents” and “Formation Path Following of Multiple Underactuated Surface Vehicles in Presence of Unknown Environmental Forces.” In these papers, Vladimir and Mitar showcased the results of research conducted as part of their masters theses, which they are working on under the mentorship of Prof. Žarko Zečević. The first paper addresses the challenge of guiding vehicles along curved paths, while the second paper tackles the problem of automatic control and guidance of a group of maritime robots in the presence of ocean currents.
