False-Alarm Detection in the Fog-Based Internet of Connected Vehicles

One of the serious security breaches that threatens today's smart technologies is the broadcasting of false alarms. These alarms may severely affect road management systems. Vehicular networks suffer from this type of threat because of the opacity and the on-purpose broadcasting of false contents which occur frequently. Modern cloud-fog communication architectures force the organization of hierarchical communications, resulting in more robust governance of disseminated contents. This paper proposes a prediction technique that is based on a binary classification using hidden Markov model (HMM). The authors' contribution in this research area are as follows: 1) modeling fog data features to enforce organization of communication, 2) proposing a technique for the automatic modeling of HMM parameters, which facilitate the precise prediction of false contents, and 3) proposing a dissemination algorithm for fast communication. The authors conducted several experiments to measure and compare the performance of the proposed model with the state-of-the-art classification algorithms. The authors also performed a misuse analysis to measure the ability of the authors' proposed model to detect false alarms in synthesis and real-world datasets. In addition, the authors conducted some further analysis to demonstrate the sensitivity of the authors' methodology to cutoff points. The results showed that the authors' HMM-based technique provides promising prediction accuracy and significantly outperforms existing classification techniques in detecting false-alarm contents.
