The current Global Positioning System (GPS) has been heavily criticized by several parties (e.g., drivers and researchers) due to the delay in disseminating en-route data to drivers ahead of time. This issue resulted in poor rates of accuracy of data (i.e., traffic status), which eventually causes inefficient transportation. According to National Institute of Standards and Technology, the delay is caused mainly by the transmission medium. This paper presents a new distributed fog-based vehicles navigation system for efficient transportation. The proposed system uses closer-to-the-source data (aka drivers) nodes (i.e., fogs) as a new transmission medium for disseminate the road details to subscribed drivers who are connected to those nodes. A package delivery scenario has been implemented to show the impact of using fog nodes in reducing the navigation time and improving efficiency. Those fog nodes gather and …
