VWS: Video surveillance on wheels using cloud in VANETs

As video gives a clear and quick understanding about any situation, it is considered to be the most reliable and recommended media for information dissemination. Real time video exchange in Vehicular Ad Hoc Networks (VANETs) can help in reducing the on road accidents and provide better road security by means of video surveillance. To execute this concept in VANET, the integrated model of VANET - Cloud Computing is the most efficient and viable solution. In this paper we propose VWS: Video Surveillance on Wheels Using Cloud in VANETs. In the proposed system, all the vehicles moving on the road serve as witnesses for various events with the help of camera equipped on board units. All the data (videos and images) of distinguished events are shared among the vehicles in a network termed as the vehicular cloud. All the data exchange that takes place in the vehicular cloud is saved in the central cloud server with the help of the roadside clouds for further surveillance and monitoring. The proposed work is supported with simulations in NS-2 and SUMO software. Implementation results of the partially designed hardware prove that the system has improved the efficiency by 75%.
