Study of Vehicular Ad-hoc NETworks (VANETs) is among challenges facing researchers today. Nodes in such networks have a relatively high speed, while there is a great shortage of the time needed for data transmission between them as a result of node speed difference as well as persistent changing of the network. Consequently, routing algorithms and modes of access to the conductor is considered as a serious challenge in such networks. In this context, researchers have introduced various protocols, including cluster-oriented methods to overcome such challenges. In cluster-oriented methods, it is of vital importance to select a sustainable cluster with due regards to the high speed and density of nodes.
