Cluster Based Neighbor Coverage Relaying (CBNCR)-A Novel Broadcasting Mechanism for Dissemination of Data in VANETs

Abstract

VANETs are emerging technology that provides road safety, traffic efficiency convenience and comfort to both drivers and passengers. Vehicular Ad hoc Network (VANET) is a subset of Mobile Ad Hoc Networks. In VANETs vehicles are equipped with embedded sensors and wireless communication capabilities providing powerful and potential applications on safety, efficiency and public collaboration while on the road. A Vehicular Sensing Network (VSN) is a type of Wireless Sensor Network (WSN) which performs traffic routing and distributed surveillance. Data dissemination in VSN is used to communicate with neighboring vehicles which requires broadcasting of data to all vehicles in the network. Usually the problem with the broadcasting is redundancy, collision and contention. To improve the reliability of message communication the aforementioned problems are to be minimized. In this paper, we propose Cluster Based Neighbor Coverage Relaying mechanism to efficiently broadcast the data to all nearby vehicles in the network. The architecture combines the features of both Cluster Based Broadcasting and Multi-hop Relaying mechanisms. The targeted approach provides an optimal solution in delivering data over VANETs.
