Abstract

The present invention provides a clustering networking method and system suitable for the dedicated network of sky-air-ground vehicles, the method includes: the aerostat node broadcasts a CH message and a Hello message, wherein the CH message is used to declare the aerostat node as a cluster The first identity, the Hello message carries the network node information table, the aerostat node has the maximum stability measure, the stability measure is obtained according to the connection degree and the average connection time of the aerostat node, the UAV node and the ground node receive the CH message, Hello message, send feedback information to the aerostat node according to the CH message and Hello message, the UAV node and the ground node are within the communication coverage of the aerostat node, and the feedback information is join request information or refuse to join information or joined information , the aerostat node determines the node in the cluster where the aerostat node is located according to the feedback information. It solves the problem of low effectiveness of railway traffic information transmission in areas with weak roadside communication infrastructure.

Description

technical field [0001] The present invention relates to the technical field of communication networking, in particular to a clustering networking method and system suitable for a dedicated network for sky-link, air-ground, and ground vehicles. Background technique [0002] my country's railways have entered a critical period of modernization, especially under the development of the "One Belt, One Road" strategy, the rapid development of railway traffic and heavy-duty railways in remote western areas. Therefore, the monitoring of railway traffic and the real-time update of railway traffic information must also be improved simultaneously to meet the needs of the full information security and operation support of the railway traffic system. At present, the transmission of my country's railway traffic information is mainly realized by connecting the train and the trackside cellular communication system to form a railway mobile communication system, thereby providing train informa...
