Description
A networked application programming project is carried out during the semester under the auspices of the course’s Virtual Laboratory. Based on Java network API methods, the project develops mechanisms to gather real-time road traffic telemetry data, measures the throughput and the response time of live connections from students’ terminals outside the University campus connected to the Virtual Laboratory Ithaki server at any time of the day and evaluates real-time statistical parameters of noise injected by the server into ad-hoc client-server connections in a student individualised manner. A technical report is submitted at the end of semester.
