【摘要】：V2G系统是在车联网技术高速发展,用户需求快速增长与有限能源之间的矛盾日益加剧,电动汽车市场占用比日趋显著等多因素作用下发展的新系统。本文以V2G系统信息传输策略作为核心问题展开了深入研究。V2G信息传输主要包含两个核心的研究内容。一方面,V2G信息报文传输方式由V2G通信系统负责。另一方面,V2G通信系统所传输的数据报文中具体的V2G业务信息则涉及资源调度算法的分配指示。本文首先提出一种基于聚合器的V2G系统通信架构,该通信架构是考虑V2G业务类型的一种异构网络融合的通信架构,其能够有效地利用现有通信网络技术服务于V2G系统。然后,本文设计了一种能够与该通信架构协同工作的资源调度算法。该算法在车辆移动模式的基础上进一步考虑用户行为,能够在最大化用户满意度的前提下最优地完成充电调度。本文所述V2G通信系统是异构无线网络系统,垂直切换决策是异构无线网络系统的关键特征。本文将针对异构无线网络的环境提出一种在考虑用户服务的基础上,促进不同无线网络系统负载均衡的垂直切换算法。该算法定义垂直切换倾向值的概念,对满足垂直切换倾向值低于垂直切换阈值的车辆进行动态切换决策以最大化实现负载均衡,有效提升带宽利用率。V2G作为近年来刚刚提出的概念还处于研究和试验阶段,V2G系统实验平台对推动V2G研究具有至关重要的作用。本文首先设计了时延测试实验,该实验通过设计基于Android的时延测试应用来测试不同网络环境的端端时延。然后,本文设计了基于NS3的V2G仿真平台协议栈,实现了协议栈中通信层所有模块功能。最后,本文通过实验数据验证了平台的有效性与实用性,并以仿真平台为基础对资源调度算法和垂直切换算法进行了仿真验证。
[Abstract]:V2G system is a new system developed with the rapid development of vehicle networking technology, the contradiction between the rapid growth of user demand and limited energy sources, and the increasingly significant market occupancy ratio of electric vehicles. In this paper, the information transmission strategy of V2G system is taken as the core problem. V2G information transmission mainly includes two core research contents. On the one hand, V 2 G message transmission mode is responsible for V 2 G communication system. On the other hand, the V2G traffic information in the data packets transmitted by the V2G communication system is related to the assignment indication of the resource scheduling algorithm. In this paper, a communication architecture of V2G system based on aggregator is proposed. The communication architecture is a heterogeneous network fusion architecture considering the type of V2G services. It can effectively use the existing communication network technology to serve V2G system. Then, this paper designs a resource scheduling algorithm which can work with the communication architecture. Based on the mobile mode of the vehicle, the proposed algorithm can further consider the user behavior and achieve the optimal charging scheduling under the premise of maximizing the user satisfaction. The V2G communication system is a heterogeneous wireless network system. Vertical handoff decision is the key feature of the heterogeneous wireless network system. In this paper, a vertical handoff algorithm is proposed to promote load balancing in different wireless network systems on the basis of considering user services in heterogeneous wireless networks. This algorithm defines the concept of vertical handoff tendency value, and makes dynamic switching decision for vehicles that meet vertical handover tendency value below vertical handover threshold to maximize load balancing. The concept of V2G which has just been put forward in recent years is still in the research and experimental stage, and the V2G system experimental platform plays an important role in promoting the V2G research. In this paper, we first design a delay test experiment, which is designed to test the end-to-end delay in different network environments by designing a delay test based on Android. Then, this paper designs the V2G simulation platform protocol stack based on NS3, and realizes all module functions of communication layer in the protocol stack. Finally, the validity and practicability of the platform are verified by the experimental data, and the resource scheduling algorithm and the vertical switching algorithm are simulated based on the simulation platform.
