A reliable communication scheme for VANET communication environments

Abstract

In VANET, the most important applications are safety applications, public infotainment and internet service to vehicles participating in it. To enable such applications efficiently communication methodologies need to prevail. Despite of its dynamic nature, VANET offers stability to some extent if identified can be useful to create efficient network communication. One of the main problems observed in VANET are loss of network connectivity. These problems could be eliminated by creating and maintaining an efficient network environment that offers wide range of connectivity, regardless of the dynamic nature of VANET. In this paper, a proposal for designing an efficient protocol to improve VANET communication using Node Velocity based Hierarchical Clustering of Nodes (NVHCN) is made. By NVHCN, cluster formation is regulated such that each cluster lives for a longer duration. Through inter-cluster communication, a reliable communication network is formed.
