Sending this information is achieved by using a routingalgorithm. A large number of cluster-based routing schemes were presented for VANET. Unfortunately,the mobility of vehicles in unexpected directions negatively affects the performance of these schemes,destroys the network links, and decreases the routes' stability. This problem leads to repeat routediscovery and maintenance operations and, as a result increases the overhead and delay. Thus, they arenot an optimal selection for safety applications. Moreover, the cluster-based policies need efficientclustering approaches, but the previous ones fail to enhance the stability of links and cluster heads.Moreover, they did not focus on the stability of gateways. Therefore, a new clustering formation approachthat focuses on the stability of cluster head and gateway is proposed. It gives priority to the parked andstopped vehicles to be cluster heads and gateways. Moreover, a new cluster-based routing protocol tobuild optimal paths with minimum delay and maximum stability called CRDS is suggested for safetyapplications. CRDS depends on the suggested clustering approach and computes the optimal routesdepending on a novel suggested optimization model. Several simulation scenarios with various mobilityspeeds and numbers of stopped and parked vehicles have been run. The results showed that CRDS isbetter than LRCA, PASRP and CVoEG according to network overhead, average end to end delay, pathstability, cluster head stability, and packet delivery ratio.
