Internet of Vehicles (IoV) engages all the components of vehicular environment from vehicle to infrastructure not only to enhance driving experience and safety but also to facilitate computation demands of IoV based applications. Due to the increasing computation demands of such applications it is difficult to facilitate vehicular environment with the existing infrastructure. However, the computing capabilities of underutilized vehicles can be used through task offloading. Therefore, it is crucial to incorporate such environment with trusted collaborative communication. Blockchain technology is gaining popularity in this regard but it is computationally expensive and high computation leads to more energy consumption. In other words, there is a trade-off between energy consumption and trusted communication. This article presents a brief literature review and a performance evaluation of earlier published fog node selection mechanism highlighting the importance of infrastructure and the energy consumption caused by the blockchain technology. The results demonstrate that it is more feasible to implement blockchain at the existing infrastructure avoiding the burden on the vehicle itself.
