Vehicular Adhoc Networks area subset of Mobile Adhoc networks,formed by high-speed moving vehicles without any permanent infrastructure. Vehicles in the network can share information with each other regarding road traffic, weather conditions, and other security information. As vehicles move at speed, frequent disconnections and dynamic topology are the main features of VANETs. Data dissemination in such an environment is quite difficult. One solution to this problem is caching. Proactively caching the data before it is requested minimizes the latency and also reduces the number of uplink requests to the server for the latest data. In this paper, we are discussing a number of cooperative caching techniques existing in VANETs
