TL;DR: This paper surveys the suitable modulation techniques for Li-Fi including those which explore time,frequency and colour domains including thoseWhich are considered to offer a practical solution forLi-Fi.
Abstract: Modulation techniques for light fidelity(Li-Fi) are reviewed in this paper.Li-Fi is the fully networked solution for multiple users that combines communication and illumination simultaneously.Light emitting diodes(LEDs) are used in Li-Fi as visible light transmitters,therefore,only intensity modulated direct detected modulation techniques can be achieved.Single carrier modulation techniques are straightforward to be used in Li-Fi,however,computationally complex equalization processes are required in frequency selective Li-Fi channels.On the other hand,multicarrier modulation techniques offer a viable solution for Li-Fi in terms of power,spectral and computational efficiency.In particular,orthogonal frequency division multiplexing(OFDM) based modulation techniques offer a practical solution for Li-Fi,especially when direct current(DC) wander,and adaptive bit and power loading techniques are considered.Li-Fi modulation techniques need to also satisfy illumination requirements.Flickering avoidance and dimming control are considered in the variant modulation techniques presented.This paper surveys the suitable modulation techniques for Li-Fi including those which explore time,frequency and colour domains.

TL;DR: In this article, a simple NOMA model with two users served by a single-carrier simultaneously is discussed, and a more general model with multicarrier serving an arbitrary number of users on each subcarrier is also discussed.
Abstract: Non-orthogonal multiple access (NOMA) has been recognized as a promising multiple access technique for the next generation cellular communication networks. In this paper, we first discuss a simple NOMA model with two users served by a single-carrier simultaneously to illustrate its basic principles. Then, a more general model with multicarrier serving an arbitrary number of users on each subcarrier is also discussed. An overview of existing works on performance analysis, resource allocation, and multiple-input multiple-output NOMA are summarized and discussed. Furthermore, we discuss the key features of NOMA and its potential research challenges.

TL;DR: Based on the philosophy of cloud computing, a new intelligently networked manufacturing model called "cloud manufacturing" has been proposed which is service-oriented, highly efficient,consumes less energy, and is knowledge based as mentioned in this paper.
Abstract: Based on the philosophy of cloud computing,a new intelligently networked manufacturing model called "cloud manufacturing" has been proposed which is service-oriented,highly efficient,consumes less energy,and is knowledge based.By integrating state-of-the-art technologies such as informatized manufacturing,cloud computing,the Internet of things,semantic Web and high performance computing,cloud manufacturing provides secure,reliable,and high quality on-demand services with low prices for users involved in the whole manufacturing lifecycle.Cloud simulation technology based on the cloud simulation platform COSIM-CSP has primarily been applied to the collaborative design of a certain multidisciplinary virtual prototype for flight vehicle.This lays the foundation for further study into cloud manufacturing.

TL;DR: This paper presents a general SDN-based IoT framework with NFV implantation in order to take advantages of SDN and NFV and help for the design of IoT architecture.
Abstract: The emerging technologies of IoT (Internet of Things), SDN (Softwar Defined Networking), and NFV (Network Function Virtualization) have great potential for the information service innovation in the Cloud and big data era. In this paper, we study the architecture models of IoT, SDN with NFV implementation. We present a general SDN-based IoT framework with NFV implantation in order to take advantages of SDN and NFV and help for the design of IoT architecture.
