Between 2018 and 2020 I participated as a Research Assistant in MultiMonD2 Project, “Platform of multi-agent intelligent systems for water quality monitoring on the Romanian sector of the Danube and Danube Delta”, contract no. 33PCCDI / 2018 (UPB project manager Prof. Octavian Fratu). I had the opportunity to develop and test communication solutions based on LoRa communication technology. Further, in 2021, out of the scope of the project, I proposed and implemented a testbed employing UAV, USV and WSN to analyze the performances of LoRa communication in a hybrid UAV-USV-WSN network.
