• At TU Delft, I hold the position of researcher, where I focus on wireless telecommunication technologies such as 4G and 5G. One of my key contributions has been the development of an end-to-end hardware setup using open-source projects. This setup is being utilized to conduct research on 4G, 5G, and beyond 5G technologies. In addition to telecommunications, I am also involved in projects related to the Internet of Things (IoT). One such project involved the development and deployment of a GDPR-compliant mmWave sensor node in the TU Delft campus. I feel fortunate to be part of a skilled team of researchers and students, and to be able to contribute to cutting-edge research and development in the areas of telecommunications and IoT.

Dec 2016 – May 2017 · 5 mos · Messina Area, Italy

• Technologies primarily worked on: BLE, WiFi(AT Commands), FreeRTOS
• Worked on the STM32F401 Nucleo and successfully built a standalone node that can extend the BLE PANs of users in a smart city scenario.
• FreeRTOS runs on the Nucleo and on top of it, BLE and WiFi logics run as threads in pre-emptive and time slicing scheduler mode.
• The node has the capability to receive data, sent from the server. The BLE module is working in observer mode (Peripheral mode also implemented) and scans for iBeacon UUIDS fields to identify the desired packet and to perform a specific function.
• The node has been implemented in various scenarios across the University of Messina campus:
• (1) Automated Lighting inside rooms,
• (2) Automating Locks on door,
• (3) Automating the exit gate of the campus.
• Created tutorials for porting the BLE and WiFi libraries on Eclipse IDE for STM32F401 Nucleo.

• Technologies primarily worked on: Contiki OS, Sensor integration, WSN430 (based on TI MSP430), I2C, SPI.
• The WSN430 nodes of the FIT platform provide support for the Contiki OS. Although the WSN430 native drivers exist, the Contiki port did not provide access to the board sensors (Temperature, and Luminosity) using the I2C and SPI bus. This limitation is due to the WSN430 hardware design, where the USART is shared between the serial port and the I2C bus.
• The objective of this internship was to add support of sensors in the Contiki OS in a seamless manner for the application, which was successfully implemented along with modification in the native drivers as well.
