Embedded systems are common in the Internet of Things domain: their integration in vehicles and mobile devices is being fostered in the Internet of vehicles (IoV). IoV has direct applications on intelligent transportation systems and smart cities. Besides basic requirements, such as ease of installation, cost‐effectiveness, scalability, and flexibility, IOV applications need to guarantee energy‐efficient and good‐quality communication. In fact, IoV implementations are commonly based on wireless nodes, which rely on a limited energy source; therefore, an efficient communication among the nodes is desirable to prolong the lifetime of the devices. In particular, the alternation of active and sleep states and the regulation of the transmission power represent two common approaches to save energy. Based on this strategy, an effective fuzzy control system is presented in the paper to manage power consumption and quality of services of IoV applications. Two fuzzy controllers increase the battery life while keeping a good throughput to workload ratio. This technique has been simulated with two leading technologies in IoV: IEEE 802.11b/g/n and IEEE 802.11p. Experimental results show a network lifetime improvement ranging from 30% to 40%, according to the adopted medium access control protocol.

车联网中节能无线设备的模糊控制系统

嵌入式系统在物联网领域很常见：它们在车辆和移动设备中的集成正在车联网（IoV）中得到发展。IoV可直接应用于智能交通系统和智慧城市。除了易于安装，成本效益，可伸缩性和灵活性等基本要求外，IOV应用还需要保证高能效和高质量的通信。实际上，IoV实现通常基于无线节点，而无线节点依赖于有限的能源。因此，需要节点之间的有效通信以延长设备的寿命。特别地，活动状态和睡眠状态的交替以及传输功率的调节是节省能量的两种常用方法。基于此策略，本文提出了一种有效的模糊控制系统来管理IoV应用的功耗和服务质量。两个模糊控制器增加了电池寿命，同时保持了良好的吞吐率与工作量之比。这项技术已通过IoV中的两项领先技术进行了仿真：IEEE 802.11b / g / n和IEEE 802.11p。实验结果表明，根据所采用的媒体访问控制协议，网络寿命可以提高30％到40％。
