Intra-Community Accessibility Methods for the Internet of Vehicles

Abstract

Due to the fact that the vehicle nodes rapidly move in the Internet of Vehicles and the topology of the Internet of Vehicles is highly dynamically changed, the Internet of Vehicles is prone to data aggregation, delay and the like, and great challenges are brought to the network communication and stability of the Internet of Vehicles to a great extent. However, a good Internet of Vehicles routing strategy not only needs to keep the rapid connection of the network, but also needs to keep the stability of the network, namely, the accessibility of the network is ensured. Therefore, the analysis and understanding of the accessibility in the Internet of Vehicles community are an urgent problem to be solved. The invention aims to solve the problems, In order to detect the communication inside theInternet of Vehicles community and keep stable, the accessibility method in the Internet of Vehicles community is provided; According to the method, a learning automaton theory is utilized, corresponding excitation functions and penalty functions are set through information exchange and competition deployed among community nodes, forwarding probabilities of different routes are adjusted in a self-adaptive mode, the Nash equilibrium state is achieved, and therefore the purposes of optimizing data transmission in the network on the whole and improving the accessibility of the Internet of Vehicles network are achieved.

Description

[0001] This invention is based on the further research and development of the patent documents previously applied for by Cheng Jiujun and other inventors on March 1, 2019, "Dynamic Evolution Method of the Internet of Vehicles Community" (applicant: Tongji University, patent application number 201910155584 2)), This prior patent document may be considered as part of the description of the present invention. technical field [0002] The invention relates to the field of the Internet of Vehicles, in particular to a method for accessibility in a community of the Internet of Vehicles. Background technique [0003] Accessibility is one of the most important characteristics of the network to achieve interconnection, mainly including connectivity and stability in the network. Connectivity is mainly to solve the reachability of point-to-point routes in the network; the focus of stability is to optimize the network structure and routing strategy to avoid network efficiency problems ca...

AI Technical Summary

Problems solved by technology

[0008] To sum up, these methods have problems in terms of connectivity and stability. When the network scale is large and the topology is highly dynamic, due to the lack of adaptive routing, it may not be able to recover quickly due to the loss of some connections, resulting in Insufficient network connectivity may also cause network congestion due to data aggregation, causing some nodes to exceed the communication load limit and fail to work normally, resulting in poor network stability
