In vehicular ad hoe networks, stable clustering methods could reduce the networks of communication relay and provide for a more efficient hierarchical network topology. This paper proposes weight-based stability clustering algorithm, in which stability neighbor sets are considered as a vehicular node weighted factor and an index of clustering re-affiliation. Meanwhile, to ensure networks load-balancing performance, by applying optimized algorithm, an optimized clusterhead （CH） sets is obtained. Simulation experiments are conducted to evaluate the performance of our algorithm in terrns of the number of CH, re-affiliation frequency and dominant set updates. The results show that our algorithm pefforrns better than the existing algorithms.
