Connectivity-based component construction method for large-scale network interconnection of the Internet of Vehicles

Abstract

In the urban scene, the large-scale network nodes of the Internet of Vehicles have a large number of nodes, frequent topology changes, and criss-crossing roads, which lead to a low degree of interconnection and coupling in the large-scale network of the Internet of Vehicles. Aiming at the above problems, considering the node redundancy characteristics of the Internet of Vehicles network, a network topology structure of the Internet of Vehicles, that is, the connected base of the Internet of Vehicles is given, and the construction method of the connected base is given by using a heuristic algorithm. This research method "a method for constructing connected base components to establish large-scale network interconnection and interoperability of the Internet of Vehicles" can effectively solve the signal interference and network congestion caused by the large-scale redundant nodes of the Internet of Vehicles in urban scenarios. The problem of low efficiency helps to improve the real-time and stability of the large-scale network interconnection of the Internet of Vehicles, and at the same time provides faster transmission efficiency guarantee for the design and operation of Internet of Vehicles application services.

Description

technical field [0001] The invention relates to the complex network field of the Internet of Vehicles. Background technique [0002] In the Internet of Vehicles, the IEEE802.11p standard is used for communication between nodes, and most distant vehicles or between vehicles and roadside infrastructure cannot communicate directly, and must rely on intermediate nodes to forward and receive messages. In the large-scale Internet of Vehicles in the urban scene, there are a large number of nodes, and the nodes have redundancy characteristics. In this way, a large number of intermediate nodes will participate in forwarding data during network communication, resulting in increased signal interference between nodes, which is likely to cause network congestion. Due to problems such as sending delays, it is difficult to guarantee network interconnection. In the case of node redundancy, if the information transmission process uses a simple flooding (Flooding) method, that is, each vehic...
