Network Simulation

Sat, 01 Jan 2022 00:00:00 +0000

ISBN 978-1439873403 | Morgan & Claypool | Amazon
This book covers all concepts in modeling and simulating wired and wireless computer networks using parallel computing to reach Internet-scale simulations.

Overview

Network Simulation

A detailed introduction to the design, implementation, and use of network simulation tools is presented. The requirements and issues faced in the design of simulators for wired and wireless networks are discussed. Abstractions such as packet- and fluid-level network models are covered. Several existing simulations are given as examples, with details and rationales regarding design decisions presented. Issues regarding performance and scalability are discussed in detail, describing how one can utilize distributed simulation methods to increase the scale and performance of a simulation environment. Finally, a case study of two simulation tools is presented that have been developed using distributed simulation techniques. This text is essential to any student, researcher, or network architect desiring a detailed understanding of how network simulation tools are designed, implemented, and used.

Intelligent Design of Structure for Function

Sat, 01 Jan 2022 00:00:00 +0000

Intelligent Design is a novel paradigm for automated, generalized, and optimized physical structural design of 3D geometry meeting a desired function.

Intelligent Design

Overview

In engineering design, an engineer starts with an initial heuristic structure and then iteratively modifies it until it satisfies all the design requirements. This lacks a thorough theoretical basis to account for the vast design space for a given problem. All current design methods are limited or biased by historical knowledge. What if this traditional design paradigm were dropped and an entirely new, unbiased, thorough framework were adopted?

Our novel Intelligent Design is the first approach to mix additive as well as subtractive steps in intelligently exploring the design space. Furthermore, it is fundamentally delinked from the traditional necessity to start with a closely related design that has been previously proven to be suitable.
