Stochastic discrete event simulation methodology is becoming increasingly popular among network researchers around the world in recent years. This is partly because of the availability of various sophisticated and powerful simulation software packages, but also because of the flexibility in model construction and validation. This paper describes our experience in using the ns-2 network simulato...

In this paper, we propose a multiconstraint-based real-time network routing scheme using simulation methodology. We first discuss how to resolve the multi-constrained path (MCP) problem with a discrete event simulation method. Our proposed Path Selection using Simulation Method (PSSM) can work with a wide class of constraints that properly include the additive constraint assumption required by ...

This article introduces the course Discrete Event Simulation – Modelling and Simulation of Computer Networks which was recently developed at the Technical University of Munich (TUM). The course is developed as part of the Tempus IV project – Modernization of Master Program Networks and Communication. The course has become very popular at TUM since it provides students with a sophisticated theor...

A new technique for the efficient asynchronous discrete eventdriven simulation of parallel shared-memory computers is proposed. Our execution-driven methodology, while introducing minimal synchronization overhead to maintain a coherent distributed event causality relation, allows complete virtualization of the design at all levels and therefore is very flexible. We give a detailed description o...

This paper presents an integrated methodology for building a virtual factory. This methodology integrates discrete event simulation directly to 3D animation with its novel methods that analyze and convert discrete simulation results into animation events to trigger 3D animation. In addition, it constructs a 3D animation framework for the visualization of discrete event simulation. This framewor...

Discrete-event simulation represents modeling, simulating, and analyzing systems utilizing the computational and mathematical techniques, while creating a model construct of a conceptual framework that describes a system. The system is father simulates by performing experiment(s) using computer implementation of the model and analyzed to draw conclusions from output that assist in decision maki...
