Mobility Management and Quality-Of-Service for Heterogeneous Networks


Book Description

Considerable attention is currently devoted worldwide towards mobility issues and challenges such as those arising from the integration of the next generation Internet over terrestrial digital TV, mobile user location management and multi-service mobile networks subject to quality of service (QoS) routing.This book follows Heterogeneous Networks: Performance Modelling and Analysis, describes recent advances in mobile and wireless networks and the Internet reflecting the state-of-the-art technology and research achievements in mobility management, performance enhancement, optimal admission control and QoS worldwide.Technical topics discussed in the book include• Mobility Management;• Optimal Admission Control;• Performance Modelling Studies;• Access Network Coverage;• Quality of Service (QoS);Heterogeneous Networks: Mobility Management and Quality of Service contains recently extended research papers, which have their roots in the series of the HET-NETs International Working Conferences focusing on the 'Performance Modelling and Evaluation of Heterogeneous Networks' under the auspices of the EU Networks of Excellence Euro-NGI and Euro-FGI.Heterogeneous Networks: Mobility Management and Quality of Service, is ideal for personnel in computer/communication industries as well as academic staff and master/research students in computer science, operational research, electrical engineering and telecommunication systems.ContentsPreface; Participants of the Reviewing Process;• Traffic Modelling and Characterisation;• Queueing and Interconnection Networks;• Performance Evaluation Studies;• TCP Performance Analysis;• Congestion Control;• Application Layer Multicast;• Numerical and Software Tools; Author Index; Keyword Index.




Providing Quality of Service in Heterogeneous Environments


Book Description

The theme of the 18th ITC is "Providing QoS in Heterogeneous Environments", addressing the interworking of old and new networking technologies. The technical programme committee received an overwhelming number of 307 submissions. Each submission has been sent for review to three international experts. In the paper committee meeting in Dresden on April 16-17th attended by 22 TPC members the final selection process has been carried out. Due to the space limitations, only 133 papers could be accepted. Thus, a large number of high quality papers could not be included in the programme. The ITC submissions reflect the current developments in telecommunications: a paradigm shift to IP related issues, heterogeneous network structures, search for new services, uncertainty toward quality of service, and service level monitoring. A clear trend is crystallised by a close look at the proceedings: In the emerging telecommunication environment, the role of teletraffic is increasingly important but has to be redefined. The topics of 6 plenary and 23 parallel sessions give an idea of the broad range of issues covered by ITC18: Next Generation Networks & MPLS; UMTS; Topology Models & Ad Hoc Networks; Traffic Characterisation & Web Performance; Network Planning & Dimensioning; Routing; Resource Allocation; Measurements; Statistical Multiplexing; Traffic Modelling; Queueing Systems; TCP Modelling; Network Planning Methods; Cellular Networks; TCP Enhancements; Optical Networks; Wireless LAN; Wireless Networks; QoS & Economics; QoS Provisioning; Admission Control & Policing; Voice over IP; Adaptive Queue Manage-ment; Application Servers.










Autonomous Control for a Reliable Internet of Services


Book Description

This open access book was prepared as a Final Publication of the COST Action IC1304 “Autonomous Control for a Reliable Internet of Services (ACROSS)”. The book contains 14 chapters and constitutes a show-case of the main outcome of the Action in line with its scientific goals. It will serve as a valuable reference for undergraduate and post-graduate students, educators, faculty members, researchers, engineers, and research strategists working in this field. The explosive growth of the Internet has fundamentally changed the global society. The emergence of concepts like SOA, SaaS, PaaS, IaaS, NaaS, and Cloud Computing in general has catalyzed the migration from the information-oriented Internet into an Internet of Services (IoS). This has opened up virtually unbounded possibilities for the creation of new and innovative services that facilitate business processes and improve the quality of life. However, this also calls for new approaches to ensuring the quality and reliability of these services. The objective of this book is, by applying a systematic approach, to assess the state-of-the-art and consolidate the main research results achieved in this area.




Recent Advances in Modeling and Simulation Tools for Communication Networks and Services


Book Description

This book contains a selection of papers presented at a symposium organized under the aegis of COST Telecommunications Action 285. COST (European Cooperation in the field of Scientific and Technical Research) is a framework for scientific and technical cooperation, allowing the coordination of national research on a European level. Action 285 sought to enhance existing tools and develop new modeling and simulation tools.




Performance Analysis of Network Architectures


Book Description

Three approaches can be applied to determine the performance of parallel and distributed computer systems: measurement, simulation, and mathematical methods. This book introduces various network architectures for parallel and distributed systems as well as for systems-on-chips, and presents a strategy for developing a generator for automatic model derivation. It will appeal to researchers and students in network architecture design and performance analysis.




Advanced Wireless Communications


Book Description

Fully revised and updated version of the successful "AdvancedWireless Communications" Wireless communications continue to attract the attention ofboth research community and industry. Since the first edition waspublished significant research and industry activities have broughtthe fourth generation (4G) of wireless communications systemscloser to implementation and standardization. "Advanced Wireless Communications" continues to provide acomparative study of enabling technologies for 4G. This secondedition has been revised and updated and now includes additionalinformation on the components of common air interface, includingthe area of space time coding , multicarrier modulation especiallyOFDM, MIMO, cognitive radio and cooperative transmission. Ideal for students and engineers in research and development inthe field of wireless communications, the second edition ofAdvanced Wireless Communications also gives an understanding tocurrent approaches for engineers in telecomm operators, governmentand regulatory institutions. New features include: Brand new chapter covering linear precoding in MIMO channelsbased on convex optimization theory. Material based on game theory modelling encompassing problemsof adjacent cell interference, flexible spectra sharing andcooperation between the nodes in ad hoc networks. Presents and discusses the latest schemes for interferencesuppression in ultra wide band (UWB) cognitive systems. Discusses the cooperative transmission and more details onpositioning.
