Dew Computing-Based Sustainable Internet of Vehicular Things

The present chapter investigates some future research cases, themes, and directions in vehicular dew computing. Dew computing is a paradigm for organizing the software and hardware of on-premises computers in a cloud computing architecture. The on-the-spot computer offers services that work independently from the cloud. It seeks to maximize the capabilities of computers on-site and cloud services. Thus it combines the concept of cloud computing with edge computing. Cloud/Fog/Edge depends on Internet connectivity. Today’s transportation and routing decisions depend on intelligent technologies. In dynamic vehicle routing and procurement planning, the Internet connectivity problem is the most important because we make a decision depending on real time, and its availability in rural/semi-urban areas is limited. To address these challenges, this investigation proposes a novel dew-caching architecture under the cloud using the Internet of vehicular things (IoVs) in different practical applications such as smart logistic routing, disaster management, etc. Also, dew computing plays a significant role in this situation. This allows the user to access the services, files, and resources when there is disrupted Internet connectivity, and then the files and resources are synced back to the cloud server when the connection is made again. The end-user gets additional freedom to retrieve essential data using dew computing. When Internet access is available, the data is synced with the master copy at the cloud server as well as in the dew server located on the user’s device. Users can read, write, update, and remove data on their smartphone, which functions as a localized version of a real server. The present study gives some novel areas of applications in dew computing utilizing caching in the Internet of vehicular things.
