Even though VANET is considered as a type of MANET, it has its own particular features that make it different from MANET. These characteristics include:
1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m.
2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network density can be very high when in a traffic jam, or very low in suburban traffic.
3. Mobility in a VANET environment is predictable because vehicles are constrained by road signs and traffic lights and how they can respond to other moving vehicles.
4. As vehicles are equipped with long life batteries, power is not a critical challenge as it is in MANET.
5. Some VANET applications have strict delay requirements to prevent drivers from possible accidents.

VANET leverages different types of wireless technologies (such as Wi-Fi, 802.11p, WiMAX, 3G among others), that had been extensively studied. These wireless technologies are an important component of Intelligent Transportation Systems.
6. Social network as big data
Social network is the collection huge datasets which comes from distinct sources. The speedy development of the big data on social network lead to a revolutionary change in user’s life and on the world-wide business. Security is also a main issue as whole the communication is through network which allow intruders to take advantage of the data [1]. As the complexity and diversity of the big data of social network is very high there are aspects how to conduct analysis of social network big data and other to ensure security through different mechanism.
Social media is the most significant sources of big data. It is not only a business option but a component from where if proper analysis be done it help it making different business strategies.
