一种面向VANET应用的信息分发方法

VANET applications developed rapidly,such as vehicle safety applications, smart parking systems. These applications use the vehicle to collect a lot of informations, in order to distribute these informations efficiently，to achieve the information rapidly and timely,this paper presents an information dissemination method based on the information Integration. In this method ,the influence factor will act on the information content. Through this, different nodes will build virtual networks logically, reach the purpose of emergency information is disseminately timely, the same category information is disseminated distinguishly. Simulation results show that the Integration-based information dissemination method improves the network bandwidth utilization, reduce the delay of acquiring effective information, verify the validity of the information dissemination method in VANET applications.
