An agglomerative approach to elect the cluster head in VANET

Abstract

The Vehicular Ad hoc Network (VANET) is the network of the mobile nodes which are connected without infrastructure. The mobile nodes requires routing that works with multi-hop characteristics. The clustering of node is needed in VANET. A cluster head is the essential part of any cluster for the efcient working of the cluster. In this work, we provide a method for the dynamically changing VANET, that elects the cluster head of the clusters and uses different parameters for the same. The QoS parameters are taken care while selecting the cluster head. The parameters involved for the same are direction of the vehicle, Speed of the vehicle, Duration for which it has been cluster head in past, Density of the Cluster, Packet Delivery ratio, Network Lifetime, Degree of the node, Transmission Range. The method proposed is the agglomerate method which involves all the parameters majorly affecting the VANET. Thus, this method will select the cluster head effectively and improves the QoS parameters of the VANET.
