EtHgSC: Eigen Trick-Based Hypergraph Stable Clustering Algorithm in VANET
Algorithm 2
The pseudocode for CH selection using the GRA model.
Input: number of clusters, number of vehicles in each cluster at each instant of time, vehicles coordinators (), current lane length (L), current direction
For t = 1: instant of time
For i = 1: clusters
For j = 1: vehicles in cluster
Calculate the CH parameters: ,, and
Predicted the next vehicle’s coordinators (X′, Y′)
Find the new vehicle’s direction from predicted coordinators
Calculate using predicted vehicle’s position
End for
