摘要：

In this paper, we study the clustering problem for crossroads in VANETs. We propose a novel Low Overhead and Stable Clustering scheme (LOSC) that considers both the stability of clusters and the communication overhead. In LOSC, a Cluster Head Electing in Advance Mechanism (CHEAM) is developed in order to select a new head for "isolated" vehicles that may not belong to a cluster. Based on CHEAM, a cluster maintenance scheme is proposed so as to reduce the number of isolated vehicles and the communication overhead. Numerical results indicate that the cluster stability and communication overhead can be significantly enhanced by our proposed clustering scheme.
