In order to overcome the high mobility problem of nodes in vehicular ad hoc networks (VANETs), the clustering algorithm can effectively improve the overall communication performance. This paper proposes an optimized timer-based passive clustering algorithm (OTPCA) for VANETs. Vehicles can choose to actively leave the cluster or not join the cluster based on the communication environment and performance. The vehicle can choose to communicate directly with the road side unit (RSU) and force it to remain for a timer. After the timer expires, it is re-evaluated whether it is suitable to join a cluster, and then repeat the operation. This can effectively solve the problem of node state stuck and improve the average communication performance. Simulation results show that the proposed algorithm is better then the passive multi-hop clustering algorithm in terms of average communication delay and control information transmission ratio.
