Embodiment Construction
[0072] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0073] The present invention is based on the traffic service information forwarding mechanism based on dynamic game theory, divides the nodes in the Internet of Vehicles into three groups, establishes a dynamic game model of the groups, and encourages the nodes in each group to choose a behavioral strategy of active cooperation through the revenue mechanism. The traffic service information in the Internet is actively released, forwarded or received. Through multiple dynamic game processes, the model reaches balance and stability, thereby effectively optimizing the data transmission environment of the entire Internet of Vehicles and helping to improve the transmission efficiency of traffic service information. Such as figure 1 shown, which includes:
[0074] Step 1. Establish a dynamic evolu...

The invention relates to a traffic service information forwarding mechanism based on a dynamic game theory, and belongs to the technical field of urban intelligent traffic information. The traffic service information forwarding mechanism based on a dynamic game theory is characterized in that based on the dynamic game theory, the multi-population dynamic evolution game theory is applied to the traffic application scene, such as traffic service information transmission, and divides the Internet of Vehicles nodes into a plurality of populations; and by means of the rewards and punishment system and evolution gaming of populations, the traffic service information forwarding mechanism encourages active publishing of node active behavior and data forwarding through earnings, and restrains the selfish behaviors of vehicle nodes so as to restrain the selfish behaviors of nodes in the Internet of Vehicles and encourage the nodes to actively take part in transmission of traffic service information. The traffic service information forwarding mechanism based on a dynamic game theory effectively improves the data transmission efficiency, and at the same time dynamically guides the Internet of Vehicles environment to tends toward a benign network state.
Description
technical field [0001] The invention relates to the technical field of urban intelligent traffic information, in particular to a traffic service information forwarding mechanism based on dynamic game theory. Background technique [0002] The Internet of Vehicles is an important part of urban intelligent transportation and a key technology to improve road efficiency and safety. Providing drivers with timely traffic service information is one of the important applications in the Internet of Vehicles. Service information includes real-time road condition information, road condition warning information, weather information, entertainment information, etc. Traffic service information can effectively improve the safety and comfort of drivers and improve traffic efficiency. Due to the changeable network topology of the Internet of Vehicles itself and the short-term connection of vehicles, the safe and reliable forwarding of traffic service information for travelers in the Internet...
