Abstract
To enable electric vehicles (EVs) to access to the Internet of Intelligent Vehicles (IoIV), charging EVs wirelessly anytime and anywhere becomes an urgent need. The resonant beam charging (RBC) technology can provide high-power and long-range wireless energy for EVs. However, the RBC system is unefficient. To improve the RBC power transmission efficiency, the adaptive RBC (ARBC) technology was introduced. In this paper, after analyzing the modular model of the ARBC system, we obtain the closed-form formula of the end-to-end power transmission efficiency. Then, we prove that the optimal power transmission efficiency uniquely exists. Moreover, we analyze the relationships among the optimal power transmission efficiency, the source power, the output power, and the beam transmission efficiency, which provide the guidelines for the optimal ARBC system design and implementation. Hence, perpetual energy can be supplied to EVs in IoIV virtually.

As a long-range high-power wireless power transfer (WPT) technology, resonant beam charging (RBC) can transmit watt-level power over long distance for the devices in the Internet of Things (IoT). Due to its open-loop architecture, RBC faces the challenge of providing dynamic current and voltage to optimize battery charging performance. In RBC, battery overcharge may cause energy waste, thermal effects, and even safety issues. On the other hand, battery undercharge may lead to charging time exten...

In this paper, we investigate flexible power transfer among electric vehicles (EVs) from a cooperative perspective in an EV system. First, the concept of cooperative EV-to-EV (V2V) charging is introduced, which enables active cooperation via charging/discharging operations between EVs as energy consumers and EVs as energy providers. Then, based on the cooperative V2V charging concept, a flexible energy management protocol with different V2V matching algorithms is proposed, which can help the EVs...

Wireless power transfer (WPT) is a promising solution to provide convenient and perpetual energy supplies to electronics. Traditional WPT technologies face the challenge of providing Watt-level power over meter-level distance for Internet of Things (IoT) and mobile devices, such as sensors, controllers, smart-phones, laptops, etc. Distributed laser charging (DLC), a new WPT alternative, has the potential to solve these problems and enable WPT with the similar experience as WiFi communications. I...

Simultaneous wireless information and power transfer (SWIPT) is an effective way for energy-constrained unmanned aerial vehicle (UAV) to prolong the network lifetime. In this paper, an amplify and forward (AF) relaying network is considered, where an energy-constrained UAV harvests energy and information simultaneously from base station and then transmits the information to the destination node. Based on time switching (TS) and power splitting (PS) architecture designing, we adopt power splittin...

Distributed laser charging (DLC) is a wireless power transfer technology for mobile electronics. Similar to traditional wireless charging systems, the DLC system can only provide constant power to charge a battery. However, Li-ion battery needs dynamic input current and voltage, thus power, in order to optimize battery charging performance. Therefore, neither power transmission efficiency nor battery charging performance can be optimized by the DLC system. We at first propose an adaptive DLC (AD...

In vehicular ad hoc networks (VANETs), cooperative data dissemination is a promising approach addressing the problem of limited connection time between vehicles and road side units. However, existing data dissemination strategies rely too much on real-time channel state information, resulting in high communication overhead and transmission delay. To reduce the communication overhead and thus enhance the system throughput, we propose a channel prediction based scheduling strategy for data dissemi...

As one of the most popular social media platforms today, Twitter provides people with an effective way to communicate and interact with each other. Through these interactions, influence among users gradually emerges and changes people's opinions. Although previous work has studied interpersonal influence as the probability of activating others during information diffusion, they ignore an important fact that information diffusion is the result of influence, while dynamic interactions among users ...

The Internet has achieved unprecedented success in human history. However, its original design has encountered many challenges in the past decades due to the significant changes of context and requirements. As a result, the design of future networks has received great attention from both academia and industry, and numerous novel architectures have sprung up in recent years. Among them, the locator/identifier (Loc/ID) split networking is widely discussed for its decoupling of the overloaded IP ad...

With the rapid development of EVs and their penetration in our modern society, the energy management issues in the smart grid integrated with EVs are attracting more and more research interest. Most of the existing literature only involves two-sided interactions between the EVs and the power grid or the smart home/buildings in the DSM investigation. In fact, however, similar to EVs, when equipped with distributed renewable energy sources and electricity storage facilities, SCs can also be regard...
