AN EXPLORATORY STUDY OF CLUSTER - BASED ROUTING PROTOCOL IN VANET: A REVIEW

Vehicular Ad Hoc Network (VANET) is a class of unusual remote ad hoc network, which has superior node portability and it can respond to rapid topology changes. Designing of optimal cluster-based multi-hop clustering approach for VANET is a major challenge due to the active change of network and link capacity. Several earlier proposed models do not consider the dynamic topology, the mobility characteristics, the limited driving direction of VANET and they require more energy. Clustering is a system for gathering nodes, making the network increasingly dynamic. With the unconsciousness of nodes, at some point, its less energy creates execution issues in network and topology changes. The main intention of the paper is to study the recent literature on optimal route-finding in VANET, also to study literature on minimizing the delay of signals between the nodes, and also to design an energy-efficient VANET. The study is carried out for network parameters such as optimal route, energy efficiency, network lifetime, etc.
