How can I get a Doctrate degree based upon my research papers without registering for PhD. ??
You cannot get a doctorate without registering, except for Honourary Doctorate.
You can however get a doctorate degree based on your research papers through the route describe here.
Is there any such degree in India or abroad which can be awarded to me based upon my research papers ??
Outside NA, you have the PhD by Publication (retrospective route). This allows you to weave a golden thread (theme) around your publications. You'll need to register officially though.
NB: there might be some in NA, but I've not come across 'em in the States or Canada.
The PhD by Publication (retrospective) is also referred to as PhD by prior published work, PhD by Published Work, and other names.
NB: the PhD by Publication (retrospective) is different from the PhD by Publication (which technically is the prospective route).
In the prospective route, you publications during your doctoral candidacy/residency counts towards your thesis. You'll write an introduction and conclusion, or you write introduction, literature review and conclusion. In some places, it is referred to as thesis by article.
In your case, if your publications are in credible outlets (typically journals) and if there's a sustained theme across them, you can approach universities.
They'll require you to submit a 7500 to 20000 words exegesis or commentary or summary or synthesis. The name, format or length varies from institution to institution.
You can look at the UK and Australia. There are others though.
You might need to note that some restrict the PhD by Publication (retrospective) to
- their staff
- their alumni
- their associate (those with strong affiliations to them).
NB: the PhD by Publication (retrospective) describe here is not the same as PhD by practice, or practice-based PhD (which are common for artefacts based disciplines; fine arts, fashion, curating, arts-writing, music et al)
