You have two options:
1) Work as an RA with some prof, and land up in a unfunded MS here (not to say, an average university considering you are not from IIT or NIT).
2) Study really hard for GATE, get into IIT or IISc for MS and MTech (considering they are mostly exam based, not prior research exp. required, it should be easy to crack). Do very well in your undergrad, probably be in top 2 or 5%, that will help you in getting MS and PhD. During MTech, not only you will get involved in research, but also have papers, personal recommendation from IIT professors, and better chances of getting into a funded program at top-notch university.
What matters is research experience, internationally published work and good references from known faculty. To me, the second option would be more preferable than the first.
However, if you are looking for high-paying job in US, above things do not apply. Its mostly for someone who ultimately wants to be in research and aims for a PhD.
