High vehicle mobility, changing vehicle density and dynamic inter-vehicle spacing are all important issues in the VANET environment. As a result, a better routing protocol improves VANET overall performance by permitting frequent service availability. Therefore, an ensemble-based machine-learning technique is used to forecast VANET mobility. Effective routing based on a hybrid metaheuristic algorithm combined with Ensemble Learning yields significantly improved results. Based on information collected from the Road Side Unit (RSU) or the Base Station, a hybrid metaheuristic (Seagull optimization and Artificial Fish Swarm Optimization) method is used to estimate (BS). The suggested approach incorporates an ensemble machine learning and hybrid metaheuristic method to reduce the latency. The current model's execution is calculated using a variety of Machine Learning techniques, including SVM, Nave Bayes, ANN, and Decision Tree. As a result, the performance of machine learning algorithms may be studied and used to achieve the best results. Comparative analysis between the proposed method (HFSA-VANET) and (CRSM-VANET was done on different performance parameters like throughput, delay, drop, network lifetime, and energy consumption to assess system performance on two factors Speed and Nodes. The HFSA-VANET method shows an overall drop in the delay of 33% and a decrease in the energy consumption of 81% and an increase of 8% in the throughput as compared with the CRSM-VANET method at 80 node. The proposed method that is HFSA-VANET has been implemented in the MATLAB and NS2 environment.
高车辆移动性、不断变化的车辆密度和动态车辆间距都是 VANET 环境中的重要问题。因此,更好的路由协议通过允许频繁的服务可用性来提高 VANET 的整体性能。因此,使用基于集成的机器学习技术来预测 VANET 移动性。基于混合元启发式算法与集成学习相结合的有效路由,可显著提高结果。基于从路边单元 (RSU) 或基站收集的信息,使用混合元启发式算法(海鸥优化和人工鱼群优化)来估计(BS)。所提出的方法结合了集成机器学习和混合元启发式方法来减少延迟。当前模型的执行使用多种机器学习技术进行计算,包括 SVM、朴素贝叶斯、ANN 和决策树。因此,可以研究和使用机器学习算法的性能以获得最佳结果。在两种因素速度和节点上,对所提出的方法 (HFSA-VANET) 和 (CRSM-VANET 进行了不同性能参数(如吞吐量、延迟、丢包、网络寿命和能耗)的比较分析,以评估系统性能。与 CRSM-VANET 方法相比,HFSA-VANET 方法在 80 个节点时的延迟总体下降了 33%,能耗降低了 81%,吞吐量提高了 8%。所提出的方法 HFSA-VANET 已在 MATLAB 和 NS2 环境中实现。
