I am currently working on reproducing a proposed scheme on the research paper "An efficient privacy-preserving data query and dissemination scheme in vehicular cloud". It occurs in a VANET. I need to simulate different vehicular nodes in the network, a Rode Side Unit(RSU) and Cloud center manager (CCM). Also I have to implement the encryption algorithm used billinear pairing. The research paper haven't covered much details of the experimental setup part. So, can anyone please suggest me any simulator or any other platform where I can simulate these?
