Toward an SDN-based Data Collection Scheme for Vehicular Fog Computing

With the integration of fog networks and vehicular networks, Vehicular Fog Computing (VFC) is a promising paradigm to the efficient collection of data for improving safety, mobility, and driver experience during journeys. To this end, we exploit the Software-Defined Networking (SDN) paradigm to propose a fully-programmable, self-configurable, and context-aware data collection scheme for VFC. This scheme leverages a stochastic model to dynamically estimate the number of fog stations to be deployed. Our simulation results demonstrate that our proposed scheme provides lower latency and higher resiliency compared to classical data collection schemes.
