摘要

由于电池容量有限和充电基础设施稀缺,电动汽车(EV)车主对续航里程的焦虑与日俱增,因此,EV-to-EV(V2V)能量共享成为延长行驶里程的重要解决方案。利用动态无线功率传输(DWPT)技术实现的车载能源网络(VEN),在行驶中的电动汽车之间共享能源变得可行。然而,有效建立通信和识别合适的 V2V 能量共享对是一项重大挑战,特别是对于有放电需求的电动汽车。为了应对这一挑战,我们提出了一种基于车载 ad-hoc 网络(VANET)的新的放电驱动能量共享协议。首先,我们提出了一种通过 VANET 传输放电信息的路由方法,其中考虑了距离、充电状态、相邻车辆数量和车速等关键因素。这种路由方案有助于在路段和交叉路口选择有效的中继节点,确保最佳通信路径。随后,我们制定了一个充电请求者选择模型,以确定最适合进行能量共享的请求者。该模型优化了个人效用,同时考虑了请求者的充电状态,确保了 V2V 能量共享的全面性和包容性。最后,我们开发了一种确认信息传输方案,以确保放电电动汽车和充电电动汽车之间完成选择确认。该方案包括转发链路故障时的恢复规定,确保在动态车辆环境中进行稳健的通信。使用网络模拟器 2(NS-2)进行的大量仿真表明,所提出的协议在数据包传送率、端到端延迟和整体 V2V 能量共享效率方面性能优越。

Discharging driven energy sharing protocol for V2V communication in vehicular energy networks

With the growing concern over range anxiety among electric vehicle (EV) owners due to limited battery capacity and sparse charging infrastructure, EV-to-EV (V2V) energy sharing emerges as a crucial solution to extend driving range. Leveraging the vehicular energy network (VEN) enabled by dynamic wireless power transfer (DWPT) technology, energy sharing among EVs in motion becomes feasible. However, the effective establishment of communication and identification of suitable V2V energy sharing pairs pose significant challenges, particularly for EVs with discharging demands. To address this challenge, we propose a new discharging driven energy sharing protocol based on vehicular ad-hoc networks (VANETs). Firstly, we present a routing approach for transmitting discharging information through VANETs, considering key factors such as distance, state of charge, number of neighbor vehicles, and vehicle speed. This routing scheme facilitates efficient relay node selection on road segments and intersections, ensuring optimal communication paths. Subsequently, we formulate a charging requester selection model to identify the most suitable requester for energy sharing. This model optimizes individual utility while accounting for the state of charge of the requesters, ensuring a comprehensive and inclusive approach to V2V energy sharing. Finally, we develop an acknowledgment message transmission scheme to ensure the completion of selection acknowledgment between discharging EVs and charging EVs. This scheme includes provisions for recovery in case of forwarding link failures, ensuring robust communication in dynamic vehicular environments. Extensive simulations conducted using network simulator 2 (NS-2) demonstrate the superior performance of the proposed protocol in terms of packet delivery ratio, end-to-end delay, and overall V2V energy sharing efficiency.

期刊介绍: Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
