Unfortunately, it is very unlikely for you to finish a PhD if you persue it to follow your father's footsteps.

And persuing a PhD is not buying a car. You cannot just list your interests and your budget, and wait someone to advise you a programme. You must already have a research topic in mind by the time you finish your MSc thesis. Or, you must be able to say that you will not pursue a PhD.

All that being said, I prefer you to pick computer networking.
