Paper citation and search on google I submitted a paper (Privacy-Preserving Smart Parking System Using Blockchain and Private Information Retrieval) on arXiv two weeks ago, and whenever I search on the paper using 
google scholar, it shows me another paper (mobile information retrieval) which 
published in 2017.

Could you please help to fix this problem?
It shows up correctly in a general Google Search. I think you just didn't wait long enough for the indexing behind the scenes.
