Network Modeling and Simulation is a practical guide to using modeling and simulation to solve real-life problems. The authors give a comprehensive exposition of the core concepts in modeling and simulation, and then systematically address the many practical considerations faced by developers in modeling complex large-scale systems. The authors provide examples from computer and telecommunication networks and use these to illustrate the process of mapping generic simulation concepts to domain-specific problems in different industries and disciplines.
Key features:
- Provides the tools and strategies needed to build simulation models from the ground up rather than providing solutions to specific problems.
- Includes a new simulation tool, CASiNO built by the authors.
- Examines the core concepts of systems simulation and modeling.
- Presents code examples to illustrate the implementation process of commonly encountered simulation tasks.
Offers examples of industry-standard modeling methodology that can be applied in steps to tackle any modeling problem in practice.
