Book Description
La voix sur LTE (Long Term Evolution) présente les mécanismes mis en oeuvre dans le réseau de mobiles 4G pour le transport de paquets IP contenant la voix et la signalisation téléphonique, ainsi que les technologies utilisées pour la fourniture du service téléphonique dans le réseau IMS (IP Multimedia Sub-system). Malgré la difficulté liée au handover du réseau 4G vers le réseau 2G/3G, l’établissement d’une communication téléphonique ne sera pas réalisé sur un réseau 4G. Cet ouvrage analyse les technologies mises en oeuvre, comme le CSFB, solution d’attente qui permet à un mobile attaché au réseau 4G de recevoir une alerte (paging) transmise par le réseau 2G/3G. Le protocole SIP sur lequel se base la signalisation téléphonique transférée par le réseau 4G, le réseau IMS qui fournit le service et définit le routage, le mécanisme SRVCC qui assure le maintien de la communication et le serveur d’applications TAS, sont également développés. L’auteur Consultant et formateur en réseaux et télécommunications, intervient auprès des industriels et des opérateurs sur des études d’architecture. Il anime des formations sur les réseaux 4G et IMS pour NEXCOM.

Book Description
Low power wide area network (LPWAN) is a promising solution for long range and low power Internet of Things (IoT) and machine to machine (M2M) communication applications. The LPWANs are resource-constrained networks and have critical requirements for long battery life, extended coverage, high scalability, and low device and deployment costs. There are several design and deployment challenges such as media access control, spectrum management, link optimization and adaptability, energy harvesting, duty cycle restrictions, coexistence and interference, interoperability and heterogeneity, security and privacy, and others.LPWAN Technologies for IoT and M2M Applications is intended to provide a one-stop solution for study of LPWAN technologies as it covers a broad range of topics and multidisciplinary aspects of LPWAN and IoT. Primarily, the book focuses on design requirements and constraints, channel access, spectrum management, coexistence and interference issues, energy efficiency, technology candidates, use cases of different applications in smart city, healthcare, and transportation systems, security issues, hardware/software platforms, challenges, and future directions.

Book Description
Modern critical infrastructures comprise of many interconnected cyber and physical assets, and as such are large scale cyber-physical systems. Hence, the conventional approach of securing these infrastructures by addressing cyber security and physical security separately is no longer effective. Rather more integrated approaches that address the security of cyber and physical assets at the same time are required. This book presents integrated (i.e. cyber and physical) security approaches and technologies for the critical infrastructures that underpin our societies. Specifically, it introduces advanced techniques for threat detection, risk assessment and security information sharing, based on leading edge technologies like machine learning, security knowledge modelling, IoT security and distributed ledger infrastructures. Likewise, it presets how established security technologies like Security Information and Event Management (SIEM), pen-testing, vulnerability assessment and security data analytics can be used in the context of integrated Critical Infrastructure Protection. The novel methods and techniques of the book are exemplified in case studies involving critical infrastructures in four industrial sectors, namely finance, healthcare, energy and communications. The peculiarities of critical infrastructure protection in each one of these sectors is discussed and addressed based on sector-specific solutions. The advent of the fourth industrial revolution (Industry 4.0) is expected to increase the cyber-physical nature of critical infrastructures as well as their interconnection in the scope of sectorial and cross-sector value chains. Therefore, the demand for solutions that foster the interplay between cyber and physical security, and enable Cyber-Physical Threat Intelligence is likely to explode. In this book, we have shed light on the structure of such integrated security systems, as well as on the technologies that will underpin their operation. We hope that Security and Critical Infrastructure Protection stakeholders will find the book useful when planning their future security strategies.
