Hello,
A lot depends upon when are you going to complete your Engineering education.There are some branches that will always stay in demand like Mechanical Engineering .

At present Artificial intelligence, robotics, materials science seem to be really promising.But to certain extent the state of various industries when you graduate will determine the scope of different branches.Along with the scope you should also focus on your interest and aptitude before deciding your branch..
Good luck.
