Abstract:

For the difficult problem of large data processing volume and strict transmission time requirement of intelligent transportation system, an end-edge collaborative system with collaborative operation of device end and edge nodes is constructed by defining the collaborative system as a complex network model. A collaborative network generation algorithm based on network node composite characteristics is proposed to achieve multi-layer complex network's sconstruction. Compared with the random geometry method, the combination of two characteristic parameters, node clustering coefficient and the betweenness centrality, to generate the collaborative network generation algorithm can describe the node characteristics more comprehensively, reflect the node importance, and improve the problem of incomplete description of node information in the existing multilayer complex network models. Finally, use four complex network models to build multi-layer network model to verify the proposed algorithm. Taking the shortest route value between nodes as evaluation indicators, the proposed node composite characteristics can significantly reduce the shortest road value between nodes in the whole network, which could reduce transmission time and improve the transmission efficiency.
