As part of my work, I had experience in working with IP protocols based on IEEE 802.11e amendment and navigation systems for vehicular networks. My responsibilities included understanding and designing suites and protocols for implementing new software.
In addition to this, I also had hands-on experience in implementing protocols for securing V2V (vehicle-to-vehicle) communication between two cars to prevent external intrusion. By implementing security protocols, including encryption and authentication measures, I ensured that communication between vehicles was protected from potential security threats.
Furthermore, I had also designed and developed a front-end page that plots modem temperature graphs across different time periods. This involved using a range of data visualization techniques, including graphing and charting libraries, to display the temperature data in an easy-to-understand format.
