[0055] The present invention and its effects will be further described below.
[0056] A combined weighted cluster head selection method suitable for VANET networks. First, node degree, distance between nodes and virtual cluster heads, node mobility, and node energy consumption are selected as clustering weighted indicators. The information obtained by a node at a certain moment, records the upper and lower bounds of each index, and calculates the information entropy of each index deviation and the weight of the dynamic entropy value of a single node; then, the linear combination weight of multiple VANET nodes The set is modeled to become a second-order norm game model, and then the multi-node dynamic entropy weight is obtained with the optimization goal of minimizing the deviation of the weight vector, and the combined weight is obtained by combining the subjective weight to complete the cluster head selection and clustering process. Specifically include the following steps: ...
