Download or read book Evaluation of HSDPA and LTE written by Markus Rupp and published by John Wiley & Sons. This book was released on 2011-11-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations With the roll-out of LTE, high data throughput is promised to be available to cellular users. In case you have ever wondered how high this throughput really is, this book is the right read for you: At first, it presents results from experimental research and simulations of the physical layer of HSDPA, WiMAX, and LTE. Next, it explains in detail how measurements on such systems need to be performed in order to achieve reproducible and repeatable results. The book further addresses how wireless links can be evaluated by means of standard-compliant link-level simulation. The major challenge in this context is their complexity when investigating complete wireless cellular networks. Consequently, it is shown how system-level simulators with a higher abstraction level can be designed such that their results still match link-level simulations. Exemplarily, the book finally presents optimizations of wireless systems over several cells. This book: Explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations Discusses the concept of testbeds, highlighting the challenges and expectations when building them Explains measurement techniques, including the evaluation of the measurement quality by statistical inference techniques Presents throughput results for HSDPA, WiMAX, and LTE Demonstrates simulators at both, link- level and system-level Provides system-level and link-level simulators (for WiMAX and LTE) on an accompanying website (https://www.nt.tuwien.ac.at/downloads/featured-downloads) This book is an insightful guide for researchers and engineers working in the field of mobile radio communication as well as network planning. Advanced students studying related courses will also find the book interesting.

Download or read book Space Air Ground Integrated Network Security written by Jianwei Liu and published by Springer Nature. This book was released on 2023-06-19 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. In this book, we review the theoretical foundations of SAGIN security. We also address a range of related security threats and provide cutting-edge solutions in the aspect of ground network security, airborne network security, space network security, and provide future trends in SAGIN security. The book goes from an introduction to the topic’s background, to a description of the basic theory, and then to cutting-edge technologies, making it suitable for readers at all levels including professional researchers and beginners. To gain the most from the book, readers should have taken prior courses in information theory, cryptography, network security, etc.

Download or read book Mobile Lightweight Wireless Systems written by Fabrizio Granelli and published by Springer Science & Business Media. This book was released on 2009-08-10 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The First International Conference on Mobile Lightweight Systems (MOBILIGHT) was held in Athens during May 18–20, 2009. The decision to organize a scientific event on wireless communications, where competition is really enormous, was motivated by discussions with some colleagues about the current unprecedented request for lightweight, wireless communication devices with high usability and performance able to support added-value services in a highly mobile environment. Such devices follow the user everywhere he/she goes (at work, at home, while travelling, in a classroom, etc.), but also result in exciting - search, development and business opportunities. Such a scenario clearly demands significant upgrades to the existing communi- tion paradigm in terms of infrastructure, devices and services to support the anytime, anywhere, any device philosophy, introducing novel and fast-evolving requirements and expectations on research and development in the field of information and com- nication technologies. The core issue is to support the desire of wireless users to have 24/7 network availability and transparent access to "their own" services.

Download or read book Access Networks written by Xiao Jun Hei and published by Springer Science & Business Media. This book was released on 2010-02-17 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid growth of the Internet as well as the increasing demand for broadband services, access networks have been receiving growing investments in recent years. This has led to a massive network deployment with the goal of eliminating the ba- width bottleneck between end-users and the network core. Today many diverse te- nologies are being used to provide broadband access to end users. The architecture and performance of the access segment (local loop, wired and wireless access n- works, and even home networks) are getting increasing attention for ensuring quality of service of diverse broadband applications. Moreover, most access lines will no longer terminate on a single device, thus leading to the necessity of having a home network designed for applications that transcend simple Internet access sharing among multiple personal computers and enable multimedia support. Therefore, the access network and its home portion have become a hot investment pool from both a fin- cial as well as a research perspective. The aim of the annual International Conference on Access Networks (AccessNets) is to provide a forum that brings together scientists and researchers from academia as well as managers and engineers from the industry and government organizations to meet and exchange ideas and recent work on all aspects of access networks and how they integrate with their in-home counterparts. After Athens in 2006, Ottawa in 2007, and Las Vegas in 2008, this year AccessNets moved to Asia for the first time.

Book excerpt: The current book provides a final report of activity performed by the COST 290 Action, ‘‘Traffic and QoS Management in Wireless Multimedia Networks,’’ which ran from March 10, 2004, until June 3, 2008. After an introduction to the COST framework and the Action’s survey time-frame and activities, the main part of the book addresses a number of technical issues, which are structured into several chapters. All those issues have been carefully investigated by the COST 290 community during the course of the project – the information presented in this book can be regarded as ultimate for each particular topic; every open research issue addressed in the book is described carefully, corresponding existing studies are analyzed and results achieved by the COST 290 community are presented and compared, and further research directions are defined and analyzed. Because the book covers a wide area of research addressing issues of modern wired and wireless networking at different layers, starting from the physical layer up to the application layer, it can be recommended to be used by researchers and students to obtain a comprehensive analysis on particular research topics including related areas, to obtain broad and ultimate referencing, and to be advised on current open issues. COST 290 is one of the Actions of the European COST Program. Founded in 1971, COST is an intergovernmental framework for European Cooperation in the field of Scientific and Technical Research, allowing the coordination of nationally funded research on a European level.
