Abstract Clustering is the process of grouping similar objects, to provide secure and stable communication in wireless network. Clustering plays a vital role in wireless networks, as it assists on some important concepts such as reusing of resources and increasing system capacity. In current research scenario, among different types of clustering, multilevel clustering is considered to the hot research topic as it is not exploited to its full potential. Multilevel clustering is the process of partitioning the nodes within the cluster in hierarchy manner. This multilevel method results in very fast clustering. Among the multilevel clustering techniques mentioned in the literature, only few of them forms the cluster with equal size. The major problem in the multilevel clustering techniques is the farthest nodes from head are not able to be communicated within the short span of time. To overcome the above-mentioned problems, this paper proposes an algorithm which satisfies the multilevel approach by combine the multi-hop and multihead concept. The proposed method of cluster is justified and implemented by using OMNET++ simulator.

1 Introduction Vehicular Ad hoc Networks (VANET) are a type of network which is emerging in peak among various wireless networks. VANET [1] is a form of Mobile Ad hoc Network (MANET) which is basically a vehicle to vehicle and vehicle to roadside communication. Now it has recently drawn significant research attention since it provides the infrastructure that enhances driver’s safety, less accidents, and avoid congestion. It also helps drivers to acquire real-time information about road conditions in prior so that they react properly on time. This prior information about road conditions and traffic helps the driver to take new routes by avoiding the vehicles to enter crash dangerous zone with the help of Vehicle to Vehicle (V2V) communication. VANET is characterized by high vehicle mobility and thus the changes in topology occur. Many control mechanisms and topology management has been proposed [1]. Clustering permits the formation of dynamic virtual backbone and it is a great challenge of clustering in highly dynamic environments. Most of the clustering algorithms for VANET
