Available in PDF, EPUB and Kindle. Book excerpt: La recrudescence et le déploiement de nouveaux services et applications dans les systèmes de communication, ainsi que le nombre toujours croissant d'utilisateurs, conduisent à une augmentation de la consommation d'énergie des réseaux et technologies de l'information et de la communication, ce qui contribue de façon significative au réchauffement climatique. Ainsi, pour satisfaire aux exigences énergétiques aussi bien pour les réseaux sans fil que filaires, de nouvelles approches doivent être développées. Dans un premier temps, nos travaux de recherche se focalisent sur les mécanismes d'allocation des ressources de systèmes point-à-point dans deux modes de transmission (mono-porteuse et multi-porteuses) avec pour objectif la minimisation de l'énergie consommée. Dans cette partie, nous présentons une nouvelle approche appelée ultra large bande (ULT) ainsi qu'un nouvelle métrique pour les systèmes de communication. En se basant sur cette nouvelle approche, des algorithmes d'allocation des ressources sont proposés afin d'améliorer l'efficacité énergétique des réseaux sans fil et des réseaux filaires, dont notamment les réseaux CPL (courant porteur en ligne).Dans un second temps, nous étudions les techniques impulsionnelles ultra large bande (ULB). Un simulateur logiciel de laisoon point-à-point ULB impulsionnelle, générique et paramétrable a été développé. L'objectif est d'améliorer l'efficacité énergétique d'une laison ULB. les différents paramètres du systèmes (largeur de l'impulsion, temps de garde, nombre d'impulsions transmises) sont exploités afin d'optimiser les performances du système.
Download or read book Green Communication in 4G Wireless Systems written by Shahid Mumtaz and published by River Publishers. This book was released on 2013-03-15 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green communication has emerged as one of the most important research topics for radio systems. This leads us to develop an energy-efficient mechanism which adjusts transmission power according to the traffic load and reduces the energy per bit usage. For the vision of Europe 2020 as a smart, sustainable and inclusive economy to become reality, the EU have set forth the 20:20:20 targets by which greenhouse gas emissions and energy reduction of primary use should be reduced by 20% while 20% of energy consumption should come from renewable resources. In fact, in today's energy-conscious society, Information and Communication Technology (ICT) accounts for 2% of the global CO2 emissions. A medium-sized cellular network uses as much energy as 170,000 homes, while the cost of powering the existing BSs accounts for a staggering 50% of a service provider's overall expenses. Therefore, new solutions are required whereby operators can accommodate additional traffic volume whilst reducing their investment in new infrastructure and beyond that significantly reduces their energy bill. Moreover, the EU political agenda, in unison with expected growth in mobile data, has identified cost and energy per bit reduction as a stringent design requirement for mobile networks of the future. Green Communication for 4G Wireless Systems mainly covers energy efficient techniques in physical, MAC and network layers. Cross-layer energy efficiency optimization in time and frequency has been also discussed with two fundamental tradeoffs, energy efficiency and spectral efficiency. This technical introduction to Green Communication in 4G wireless systems, explaining the rather complex standards (3GPP Releases R10 and R11), is a must-read for engineers, decision-makers and students interested in Green Communication, as well as other researchers and scientists from this evolving field.

Download or read book Mobile and Wireless Communications written by Salma Ait Fares and published by BoD – Books on Demand. This book was released on 2010-01-01 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical hazards, etc. Moreover, the radio frequency (RF) transceiver nodes of such networks require the design of transmitter and receiver equipped with high performance building blocks including antennas, power and low noise amplifiers, mixers and voltage controlled oscillators. Nowadays, the researchers are facing several challenges to design such building blocks while complying with ultra low power consumption, small area and high performance constraints. CMOS technology represents an excellent candidate to facilitate the integration of the whole transceiver on a single chip. However, several challenges have to be tackled while designing and using nanoscale CMOS technologies and require innovative idea from researchers and circuits designers. While major researchers and applications have been focusing on RF wireless communication, optical wireless communication based system has started to draw some attention from researchers for a terrestrial system as well as for aerial and satellite terminals. This renewed interested in optical wireless communications is driven by several advantages such as no licensing requirements policy, no RF radiation hazards, and no need to dig up roads besides its large bandwidth and low power consumption. This second part of the book, Mobile and Wireless Communications: Key Technologies and Future Applications, covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. We hope that this book will be useful for students, researchers and practitioners in their research studies.
