I am really frustrated, I have started my research for my master thesis 6 months ago and I have to submit the final draft after 2 months.
I was interested in a specific topic and I looked for a supervisor with the same research interests.
I was looking for something related to internet security (Botnet Detection); luckily, my supervisor gave me a research plan exactly about what I wanted to do. However, a month later and after I submitted the proposal and started to read deeply about the topic; I found that exactly the same research had already done by another two PhD students and what I was supposed to do was 100% repeating what they already had done 2 years ago.
I directly contacted my supervisor explaining to him the situation. I discovered that my research plan is exactly the same (word by word, someone copied from other). Moreover, the topic itself is very specific and is not easy to build or modify on it, he said "No problem, you just repeat it and we will try to slightly modify something.", then he added "If you can not do that, it is enough to repeat it." and I just agreed (trying to be positive and avoiding problems).
Now, after I started my writing I found myself repeating the same ideas and the same experiments, the same statements and the same conclusions. Later on, I discovered that this research supposed to be done by adviser with the group who already published the work and for some reasons they excluded him.
In short, the supervisor did not mention that this work is already published and did not mention that he was team member with them.
What I shall do?
Now I feel this work is 100% not original and I will not add and contribute anything. I am not feeling happy by wasting my time doing something like that.
Shall I escalate the story to the general adviser for master's students? Should I change the topic or should I continue and defend others work claiming that this is my own work?
I am not scared of rejecting my thesis, I am totally not satisfied about what I do write now. I am doing my masters to add something to my knowledge, experience and to feel really I will be one step a head.
Note: I work in industry field and I have no experience in academic and research fields.
