PV-DVMC: a novel path visibility based reliable data dissemination in VANETs using machine learning with layered clustering
摘要
The vehicle obtains the related information through VANET dissemination. However, the lack of consideration of visibility perspective and real-time circumstances in dissemination protocols development has a significant impact on the programs aimed at preventing accidents and ensuring human safety. In order to address the challenge of information dissemination based on dynamic visibility conditions, a cluster-based approach PV-DVMC is employed to effectively capture and model dynamism in dissemination according to current visibility when considering the mobility of vehicles. Proposed PV-DVMC is a novel method that aims to offer a dynamic dissemination strategy for varying and unpredictable real-time visibility conditions encountered by drivers and vehicles during motion. Additionally, we deploy the layering method in the cluster to reduce complexity and communication overhead. We further proposed DPLD; the predictive machine-learning model on a selected cluster to predict the layers based on classification and regression decision-tree approach for multiple visibility factors. PV-DVMC efficiency was assessed through simulations. In comparing other standard cluster based strategy without visibility perspective performance of the proposed is improved by reducing delay and collision ratio to 46.23% and 38.64% respectively, while the ratio of delivery of messages increases by 42.82%. Further the nuScene Dataset is utilized for dynamic visibility scenarios to evaluate the accuracy, precision, recall and F1-score performance of our proposed method.
