Roadside units (RSU's), that modify vehicles-to-infrastructure communications, area unit deployed on roadsides to handle the ever-growing communication demands caused by explosive increase of conveyance traffics. A way to with efficiency utilize them to reinforce the conveyance Cloud network (VCE) performance area unit the necessary issues in planning RSU-aided VCE's. In this work, we tend to implement an intensive experiment our underlying algorithms model file transfers among nodes as a weighted graph, and maximize the chance of storing information things of comparable privacy preferences within the same region. We tend to equip every cloud node with a socket monitor that's capable of watching the period communication among cloud nodes. Supported the period information transfer data captured by the socket monitors, our system calculate the chance of a given transfer to be outlawed. Specifically, we discover that the contact time between RSUs associate degreed  vehicles obeys an exponential distribution, whereas, the contact rate between them follows a distribution. In step with these observations, we tend to investigate the matter of communication contact-aware mobile information replication for RSU-aided VCEs by considering the mobile information dissemination system that transmits information from the net to vehicles via RSUs through expedient communications. In explicit, we tend to formulate the communication contact-aware RSU-aided conveyance mobile information dissemination drawback as associate degree improvement drawback with realistic VCE settings, and that we give an associate degree economical heuristic answer for this NP-hard drawback. By completing in depth simulation exploitation realistic conveyance traces, we tend to demonstrate the effectiveness of our planned heuristic contact-aware information replication theme, as compared with the best answer and different existing schemes.
