Research on traffic information transmission algorithm in internet of vehicles

Yan, Chao / Wang, Jian / Li, Zhongkui

In internet of vehicles (IOV), on-board Ad hoc network between vehicles is established randomly and freely based on dedicated short range communication technology, enabling the vehicles beyond visual range of drivers and signal transmission range of on-board communication equipment to establish communication connection for transmission and sharing of information and data through single-hop and multi-hop transmission. The current several routing protocols of Ad hoc network have their own advantages and disadvantages, therefore revision is still necessary to meet communication requirement and apply in various scenes of internet of vehicles. Based on communication requirement between vehicles under IOV environment, traditional zone routing protocol(ZRP) was improved and topology maintenance algorithm and routing searching algorithm between vehicles were put forward in the paper, and assessment to algorithm through OPNET modeler stimulation software was conducted. The result displayed that the improved ZRP routing protocol algorithm has promoted information transmission rate and efficiency, and reduced network energy consumption with good performance, which meets the information transmission need in internet of vehicles.
