Study of a WSN cooperation vehicle information collection method

Intelligent transportation system (ITS) is an effective way to solve the increasingly serious traffic problems. It is also the development direction of traffic system in the future. The collection technology of road traffic information is one of the key technologies of ITS. Vehicle information can be obtained by the communication between vehicles and RSUs which is deployed on the side of the road. But the deployment cost of RSUs is higher. In the view of the shortage of the current information collection method, the collection method and the related technology of road traffic information have been researched in this paper, and a traffic information collection method based on WSN have been discussed. The emphasis is the data collecting and processing, and the routing strategy based on node correlation degree. Finally, the effectiveness of the scheme is analyzed.
