Vehicular Ad-hoc NETwork (VANET) is an infrastructure less network with no fixed routers, hosts or wireless base stations and relies on the vehicles themselves to provide network functionality. In VANETs vehicles (OBU On Board Unit) communicate with each other and with Road Side Units (RSU) to access data. But due to high mobility of nodes and frequent disconnections of networks, nodes remain in the range of each other only for a short period of time and unable to access the data. Data dissemination is an approach which is supposed to increase data availability by utilizing RSU's and OBU's both as data distributors.
