Recently, Vehicular Ad hoc Networks (VANETs) is focused on by many researchers. VANET’s specific characteristics like high-speed, unstable communication link, network partitioning, and information transfer become a hard challenging problem. Access control depends on IEEE 802.11p and has been used for Vehicle to Everything (V2X) and Vehicle to Vehicle (V2V) communications. The high dynamics of VANET nodes which will cause frequent disconnection of links and even partitioning of networks causes the source vehicle is lost their message of data that disseminated to the destination region, and also may lead to the message redundancy, causing a broadcast storm. One of the suggested solutions for this in VANET is the clusters. This paper will focus on the dissemination of cluster-based data. The clustering algorithm is provided according to the highway road, the proposed algorithm seeks to increase the network stability by identifying the Cluster Head (CH) periodically. By using a suggested variable range of cluster head (R-of-CH) in this paper to be a measure of finding the CH for each new vehicle. The simulation results are performed by NetLogo, under different vehicle densities and different values of (R-of-CH). The results of the simulation show the proposed algorithm contributes to making the network more stable with a high delivery rate as the disseminated messages will reach all vehicles in the simulated area. It indicates that the coverage rate is also high and the lost message rate is very low.
