BOOST: A Connected Dominant Set-Aware Energy-Efficient Scheme for Software Defined Connected Autonomous Vehicular Networks

In recent years, advancements in vehicular communication has improved road safety along with passenger convenience for many applications. However, to take intelligent and timely decisions, a large number of complex operations need to be get executed on large amount of data base repositories which in turn generates a huge burden on the underlying network infrastructure leading to a large amount of energy consumption. Most of the existing solutions reported for the aforementioned problems are based upon the traditional monolithic solutions which may not be applicable in modern scenarios in this environment. Hence, to mitigate the aforementioned challenges and constraints, in this article, we propose BOOST, a connected dominating set (CDS)-aware energy-efficient clustering scheme for Software Defined Network by integrating V2I and V2V communications for reliable and seamless data delivery. The proposed scheme has been specifically designed for urban scenario to achieve effective data delivery with minimum energy consumption. By leveraging the benefits of CDS on roadside communication infrastructure, BOOST is able to adapt with varying traffic conditions to provide seamless scalability with minimum energy and network overheads. The proposed scheme has been evaluated using various performance evaluation metrics in comparison to the existing benchmark schemes. The results obtained demonstrate its superior performance by 3% to 4% in terms of energy-efficiency, network overhead, packet delivery rate, and network throughput in comparison to the existing benchmark schemes.
