Clustering networking method and system suitable for special network of sky-near air-ground vehicle

Abstract

The invention provides a clustering networking method and a system suitable for a special network of a sky-near air-ground vehicle, The method comprises: a floater node broadcasts a CH message and a Hello message, wherein the CH message is used for declaring the floater node as the cluster head identity, the Hello message carries a network node information table, the floater node has a maximum stability metric, the stability metric is derived from the connectivity of the floater node and the average connection time, the CH message and Hello Message are received by the UAV node and the ground node, feedback information is sent to the floater node according to the CH message and the Hello message, the UAV node and the ground node are in the communication coverage range of the floater node, the feedback information is the join request information or the join refusing information or the joined information, and the floater node determines the node in the cluster where the floater node is located according to the feedback information. The invention solves the problem that the efficiency of railway traffic information transmission is low in areas where the roadside communication infrastructure is weak.

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...
