Cluster-based cooperative transmission mechanism in vehicular ad hoc network

为提高公路车辆的数据服务效率和通信服务的能量利用率,将分簇算法应用于实际环境的数据传输,提出一种新的传输机制。针对公路环境,应用分簇和数据聚合,进行了实时的双向数据协作传输在公路上的应用设计。仿真结果表明:在公路环境中,整合了分簇和数据聚合的数据传输机制能有效提高服务率、减少服务时延、提高吞吐量并减少能耗。

In order to improve the data service efficiency of highway vehicles and the energy utilization of communication services,the clustering algorithm was applied to data transmission in practice,and a new transmission mechanism was proposed.Aiming at the highway environment,application clustering and data aggregation were employed in the application design of real-time two-way data cooperative transmission on the highway.Simulation results show that in the highway environment,the data transmission mechanism that integrates clustering and data aggregation can effectively improve service rate,reduce service delay,increase throughput and reduce energy consumption.
