Abstract
Nowadays, message propagation has been one of the major tasks of Vehicular Ad-Hoc Networks (VANETs). The main obstacle of message propagation, which relies on the data forwarding among vehicles, is the frequent change in network topology, as the intermittent link between the vehicles will degrade the performance of message propagation. Hence, RSUs are deployed to extend vehicle coverage and improve network performance in VANETs. However, non-optimal RSU deployment may result in greater power consumption and lower quality of network performance. In this paper, we study the vehicle mobility characteristics along the highway and propose a Cluster-based RSU Deployment (CRD) scheme with the Traffic-Aware Power Control (TAPC) method to maximize the network performance, as well as minimizing the energy consumption of RSUs. Moreover, we develop a data propagation algorithm, Data-Driven Message Propagation (DDMP), to improve the performance of message propagation in RSU-assisted VANETs. The performance of the proposed scheme is analytically evaluated by comparing performance in with and without our scheme scenarios. Through extensive simulations, with the aid of our scheme, the performance of message propagation is improved significantly, in terms of the propagation latency and the power consumption.
目前,消息传播已成为车载自组织网络(vanet)的主要任务之一。消息传播依赖于车辆之间的数据转发,其主要障碍是网络拓扑结构的频繁变化,车辆之间的间歇性链路会降低消息传播的性能。因此,部署rsu以扩大车辆覆盖范围并提高vanet的网络性能。然而,非最优RSU部署可能会导致更大的功耗和更低的网络性能质量。本文研究了高速公路上车辆的移动特性,提出了一种基于交通感知功率控制(Traffic-Aware Power Control, TAPC)方法的基于集群的RSU部署(CRD)方案,以最大化网络性能,同时最小化RSU的能耗。此外,我们还开发了一种数据传播算法——数据驱动消息传播(DDMP),以提高rsu辅助VANETs的消息传播性能。通过比较有和没有我们的方案方案的性能,分析地评估了所提出方案的性能。通过大量的仿真,我们的方案在消息传播延迟和功耗方面有了明显的提高。
