Fourth Generation Wireless Systems: Requirements and Challenges for the Next Frontier

Fourth generation wireless systems (4G) are likely to reach the consumer market in another 4-5 years. 4G comes with the promise of increased bandwidth, higher speeds, greater interoperability across communication protocols, and user friendly, innovative, and secure applications. In this article, I list the requirements of the 4G systems by considering the needs of the users in the future. These requirements can be met if technical and business challenges can be overcome. Technical challenges include mobility management, quality of service, interoperability, high data rate, security, survivability, spectrum, intelligent mobile devices, middleware, and network access. I discuss the most plausible solutions to these technical challenges in this paper. Business-related challenges include billing, payment methods, pricing, size of investments, content provision and mediation, and the trade-off between richness and reach. If these technical and business challenges can be met, then 4G will become the next frontier in data and voice communication infrastructure

Delivery of Personalized and Adaptive Content to Mobile Devices:A Framework and Enabling Technology

Many innovative wireless applications that aim to provide mobile information access are emerging. Since people have different information needs and preferences, one of the challenges for mobile information systems is to take advantage of the convenience of handheld devices and provide personalized information to the right person in a preferred format. However, the unique features of wireless networks and mobile devices pose challenges to personalized mobile content delivery. This paper proposes a generic framework for delivering personalized and adaptive content to mobile users. It introduces a variety of enabling technologies and highlights important issues in this area. The framework can be applied to many applications such as mobile commerce and context-aware mobile services

Quadri-dimensional approach for data analytics in mobile networks

The telecommunication market is growing at a very fast pace with the evolution of new technologies to support high speed throughput and the availability of a wide range of services and applications in the mobile networks. This has led to a need for communication service providers (CSPs) to shift their focus from network elements monitoring towards services monitoring and subscribers’ satisfaction by introducing the service quality management (SQM) and the customer experience management (CEM) that require fast responses to reduce the time to find and solve network problems, to ensure efficiency and proactive maintenance, to improve the quality of service (QoS) and the quality of experience (QoE) of the subscribers. While both the SQM and the CEM demand multiple information from different interfaces, managing multiple data sources adds an extra layer of complexity with the collection of data. While several studies and researches have been conducted for data analytics in mobile networks, most of them did not consider analytics based on the four dimensions involved in the mobile networks environment which are the subscriber, the handset, the service and the network element with multiple interface correlation. The main objective of this research was to develop mobile network analytics models applied to the 3G packet-switched domain by analysing data from the radio network with the Iub interface and the core network with the Gn interface to provide a fast root cause analysis (RCA) approach considering the four dimensions involved in the mobile networks. This was achieved by using the latest computer engineering advancements which are Big Data platforms and data mining techniques through machine learning algorithms.Electrical and Mining EngineeringM.

Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities

Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elements in generation, transmission, distribution and loads. This paper discusses some of the challenges and opportunities of communications research in the areas of smart grid and smart metering. In particular, we focus on some of the key communications challenges for realizing interoperable and future-proof smart grid/metering networks, smart grid security and privacy, and how some of the existing networking technologies can be applied to energy management. Finally, we also discuss the coordinated standardization efforts in Europe to harmonize communications standards and protocols.Comment: To be published in IEEE Communications Surveys and Tutorial

Mobile telecommunication networks and mobile commerce : towards its applications in chinese market

La télécommunication mobile connecte les personnes de n'importe où à tout moment. La transmission de la voix et des données à travers les réseaux de télécommunication mobile permet d'envoyer des informations et de diriger des transactions d'une manière nouvelle. Cela crée un nouveau domaine d'affaires qui s'appelle du commerce mobile, une affaire étendue basée sur l'Internet avec de nombreux des caractéristiques uniques ajoutés. Comme un soutien fondamental du plate-forme, les réseaux de la télécommunication mobile joue un rôle essentiel dans le commerce mobile. Leurs caractéristiques techniques et le déploiement déterminent l'essence pour le commerce mobile. Dans cette mémoire, nous étudions et présentons les caractéristiques techniques des technologies communications mobiles du réseau 1G à 3G et au-delà. Nous étudions également les technologies WLAN et WAP qui sont courantes dans le commerce mobile en Chine et dans le monde. Le commerce mobile est en train de se développer, le nombre d'utilisateurs de téléphones mobiles sont de plus en plus en Chine et dans ce monde. Les utilisateurs mobiles énormes en Chine ainsi que la maturité des technologies 3G affichent un fort potentiel pour offrir et d'adopter plus les nouveaux services mobiles. Après réviser l'évolution du commerce mobile et l'histoire du succès i-mode au Japon, nous nous concentrons sur le mobile du marché chinois de manière à découvrir son marché, l'infrastructure du réseau mobile, et le modèle d'affaires. Fondé sur la base de notre enquête sur le commerce mobile chinois, nous présentons, selon notre jugement, les services mobiles et des applications que sont convenables pour la Chine. Parmi eux, nous pensons qu'il y a la tendance sur les services basés sur la localisation et services orientées de l'architectures. Cette tendance peut attirer plus d'attention à offrir de nouveaux services. En plus, elle peut offrir des services d'intégration et de personnalisation qui viennent de fournisseurs de services mobiles et des utilisateurs finaux. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Gestion intégrée et écosystémique, Principe de précaution, Communication entre acteurs, Risques sur l'environnement et la santé

New Waves of IoT Technologies Research – Transcending Intelligence and Senses at the Edge to Create Multi Experience Environments

The next wave of Internet of Things (IoT) and Industrial Internet of Things (IIoT) brings new technological developments that incorporate radical advances in Artificial Intelligence (AI), edge computing processing, new sensing capabilities, more security protection and autonomous functions accelerating progress towards the ability for IoT systems to self-develop, self-maintain and self-optimise.

Robust Home Care Access Network

Abstract Critical networks e.g. telecare services, telemonitoring, are implemented to provide the information security and reliability that the end user desires, especially during an emergency. Unlike business carrier systems that are planned for the general public's use, critical communication systems are designed particularly for public protection and other serious communication situations. Availability and reliability of such networks is highly desirable. The following thesis works to compare and analyze a variety of communication access technologies to find out the best primary means of data transportation for health critical services and model reliable communication link by using redundancy. This study also provides an efficient failover mechanism to implement redundant links. This strategy is intended to provide the reliable communication and to protect the established communication link
