KEY FEATURES - Installing NS2 and running simple examples - Creating and incorporating the network module - All the built-in NS2 modules are explained in a comprehensive manner - Details of Network AniMator (NAM) and Xgraph - Simple language, crystal clear approach, and a straightforward comprehensible presentation - The concepts are duly supported by several examples WHAT WILL YOU LEARN Readers will get to know a conspicuous difference of how NS2 is being utilized as a product device in research and business applications. Today, applying network simulations does not require a PhD. Nonetheless, there are a couple of assets out there that completely cover all the essential parts of actualizing networking and communications, without expecting you to take the advanced math courses. We believe that this book will help any individual who needs to apply network simulation, without studying years of analytics, calculus math, and probability hypothesis. WHO THIS BOOK IS FOR The book is basically meant for all those graduate and research students who find the algorithms and protocols of networking and communications difficult to implement. In this book, all basic protocols of networking and simulation are discussed in detail with a practical approach. Primarily, beginners can find this book more effective as the chapters are sub-divided in such a way that they will find building and implementing algorithms in NS2 interesting and easy.

Available in PDF, EPUB and Kindle. Book excerpt: NS-2 is an open-source discrete event network simulator which is widely used by both the research community as well as by the people involved in the standardization protocols of IETF. The goal of this book is twofold: on one hand to learn how to use the NS-2 simulator, and on the other hand, to become acquainted with and to understand the operation of some of the simulated objects using NS-2 simulations. The book is intended to help students, engineers or researchers who need not have much background in programming or who want to learn through simple examples how to analyse some simulated objects using NS-2. Simulations may differ from each other in many aspects: the applications, topologies, parameters of network objects (links, nodes) and protocols used, etc. The first chapter is a general introduction to the book, where the importance of NS-2 as a tool for a good comprehension of networks and protocols is stated. In the next chapters we present special topics as TCP, RED, etc., using NS-2 as a tool for better understanding the protocols. We provide in the appendices a review of Random Variables and Confidence Intervals, as well as a first sketch for using the new NS-3 simulator.

Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of Web-based learning and new concepts like virtual cla- rooms, virtual laboratories and virtual universities, many issues need to be addressed. On the technical side, there is a need for effective technology for deployment of W- based education.On the learning side, the cyber mode of learning is very different from classroom-based learning. How can instructional developmentcope with this new style of learning? On the management side, the establishment of the cyber university - poses very different requirements for the set-up. Does industry-university partnership provide a solution to addressing the technological and management issues? Why do we need to standardize e-learning and what can we do already? As with many other new developments, more research is needed to establish the concepts and best practice for Web-based learning. ICWL 2004, the 3rd International Conference on Web-Based Learning, was held at the Tsinghua University (Beijing, China) from August 8th to 11th, 2004, as a continued attempt to address many of the above-mentioned issues. Following the great successes of ICWL 2002 (Hong Kong) and ICWL 2003 (Australia), ICWL 2004 aimed at p- senting new progress in the technical, pedagogical, as well as management issues of Web-based learning. The conference featured a comprehensive program, including a tutorial session, a keynote talk, a main track for regular paper presentations, and an - dustrial track. We received 120 papers and accepted only 58 of them in the main track for both oral and poster presentations.

Book excerpt: Networked Graphics equips programmers and designers with a thorough grounding in the techniques used to create truly network-enabled computer graphics and games. Written for graphics/game/VE developers and students, it assumes no prior knowledge of networking. The text offers a broad view of what types of different architectural patterns can be found in current systems, and readers will learn the tradeoffs in achieving system requirements on the Internet. It explains the foundations of networked graphics, then explores real systems in depth, and finally considers standards and extensions. Numerous case studies and examples with working code are featured throughout the text, covering groundbreaking academic research and military simulation systems, as well as industry-leading game designs. Everything designers need to know when developing networked graphics and games is covered in one volume - no need to consult multiple sources. The many examples throughout the text feature real simulation code in C++ and Java that developers can use in their own design experiments. Case studies describing real-world systems show how requirements and constraints can be managed.
