This book is an essential guide to IPv6 network slicing. It covers both the fundamentals and cutting-edge technologies of IPv6 network slicing, and provides insights into future industry developments. IP network slicing is an architectural innovation that provides multiple dedicated logical networks on a shared physical network. It comprises a complete set of solutions designed to meet the differentiated service requirements of the 5G and cloud era. This book focuses on IP network slicing based on the data plane of IPv6, a second-generation network layer protocol standard designed to address many of the problems encountered with IPv4. The book explores the technical implementation of IPv6 network slicing by introducing its architecture, implementation solutions, resource partitioning technologies, data plane technologies, and control plane technologies. The development of 5G gave rise to the emergence of network slicing, which was initially applied to 5G mobile transport networks and then extended to support fixed and enterprise services. Today, it can also be applied to IP metro and backbone networks. Currently, IP network slicing, which plays an important role in supporting the 2B services of carriers, is being widely applied and deployed. In terms of realizing the IP‑based Service‑Level Agreement (SLA) guarantee, IP network slicing can be considered a significant leap forward. Initially, IP networks used Quality of Service (QoS) technologies such as DiffServ to guarantee service quality on single devices. Later, Traffic Engineering (TE) technologies such as Multiprotocol Label Switching (MPLS) TE were developed to provide service quality guarantee through TE paths. Now, IP network slicing is introduced to guarantee service quality through network‑wide resource isolation. Moreover, compared with establishing physical private networks, deploying IP network slicing helps to significantly reduce costs. IPv6 plays a pivotal role in IP network slicing.

It also includes discussions on various materials used for practical antenna design which are suitable for 5G, beyond 5G applications, and cell-free massive MIMO systems. Various latest techniques used in 5G and beyond 5G communication, such as non-orthogonal multiple access (NOMA), device-to-device (D2D) communication, 6G ultra-dense O-RAN, rate-splitting multiple access (RSMA), simultaneous wireless information and power transfer (SWIPT), massive multiple input multiple output (mMIMO), and cell-free massive MIMO systems are explained in detail for 5G and beyond cellular networks. Design and development aspects for 5G and beyond networks over various techniques are also included in this book. The different emerging research areas in 5G and beyond wireless networks, probable solutions, and future research directions have been elaborated. The role of metalens in designing effective antennas and material specifications for 5G applications has been explained in this book. Apart from the above emerging topics, this book also gives ideas about intelligent communication, Internet of Multimedia Things (IOMT), millimeter-wave MIMO-UFMC, and fog computing cloud networks. The last chapter gives details about the legal frameworks for 5G technology for responsible and sustainable deployment.

Название: Incentive Mechanism for Mobile Crowdsensing: A Game-theoretic Approach

Mobile Crowdsensing (MCS) is emerging as a novel sensing paradigm in the Internet of Things (IoTs) due to the proliferation of smart devices (e.g., smartphones, wearable devices) in people’s daily lives. These ubiquitous devices enable the possibility of harnessing the wisdom of crowds by recruiting mobile users to collectively perform sensing tasks that largely collect data about a diverse range of human activities and the surrounding environment. However, users suffer from resource consumption like battery, computing power, and storage, which discourage users’ participation. To ensure a participation rate, it is necessary to employ an incentive mechanism to compensate users’ costs such that users are willing to take part in crowdsensing. Designing an appropriate incentive mechanism is nontrivial due to different practical challenges like modeling and computational hardness. Capturing the different roles’ utility maximization, game theory is widely used to address incentive mechanism design problems. While many existing papers study incentive mechanism in MCS, to the best of our knowledge, there is few books giving a comprehensive review of the incentive mechanism for MCS, especially from the game-theoretic perspective. This book aims to fill this void. The prerequisite for reading this book is a basic understanding of the mobile crowdsensing infrastructure, game theory, equilibrium analysis, and convex optimization.
