Embodiment

[0114] The results of this experiment were divided into two groups. Investigate the two parameters of data packet delivery rate and average end-to-end delay respectively, in the original AODV protocol, AODV protocol with incentive mechanism and discount factor of 0.6 (0.6AODV) and ADOV protocol with incentive mechanism and discount factor of 0.8 (0.8AODV) In these two cases, with the increase of the proportion of selfish nodes in the network, the changes of various parameters are analyzed to obtain the performance of the incentive mechanism.

[0115] Such as figure 2 As shown, the change of packet delivery rate is given when the proportion of selfish nodes in the network increases under the three cases of AODV protocol without incentive mechanism, AODV protocol with discount factor of 0.6 and AODV protocol with discount factor. It can be seen from the simulation diagram that these three cases have one thing in common, the packet delivery rate decreases with the increase of t...

Abstract

The invention discloses an Internet of Vehicles node excitation method based on a game model. A new incentive mechanism is provided on the basis of a game model, nodes with high contribution degree are rewarded on the basis of reputation values of the nodes, the nodes with low contribution degree are punished, the problem that the contribution degrees among the nodes are inconsistent is solved, and the enthusiasm of all the nodes is improved. The vehicle network node can be stimulated to actively participate in the data packet forwarding task of the network, the data packet delivery rate is improved on the basis of the original AODV protocol, the average end-to-end time delay is reduced, and the overall network performance of the Internet of Vehicles is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle node communication in the Internet of Vehicles, and relates to an incentive method for a node in the Internet of Vehicles based on a game model. Background technique [0002] With the continuous development of the economy, people's living standards are steadily improving. For the convenience of travel, more and more families use cars as means of transportation. As of the first half of 2018, the number of motor vehicles in China has exceeded 300 million, of which 217 million are cars. While cars bring convenience to people, they also cause many social problems. For example, frequent traffic accidents, traffic congestion and air pollution. Therefore, there is an urgent need for a vehicle communication technology to alleviate the above problems. In recent years, the emergence of Internet of Vehicles technology has provided answers to these questions. [0003] The Internet of Vehicles is develope...
