The paper describes an e cient versatile and extensible software tool for the analysis of the quality of connectionless services in ATM networks The tool is named CLASS for ConnectionLess ATM Services Simulator CLASS is a time driven slotted synchronous simulator entirely written in standard C language CLASS allows the performance analysis of ATM networks adopting the viewpoint of both the end ...

One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...

The rapidly increasing traffic demand from mobile users forces network operators and service providers to extend and optimize existing networks as well as to plan entirely new mobile radio networks. Current planning methods rely on static coverage prediction. The optimization is partly based on measurements and gathered experiences in connection with empirical methods. However, these methods do...

YANNS (Yet Another Neural Network Simulator) is a new object-oriented neural network simulator for feedforward networks as well as general recurrent networks. The goal of this project is to develop and implement a simulation tool that satisfies the following constraints: flexibility, ease of use, portability and efficiency. The result is a simulator with the kernel implemented as a collection o...

The vehicular safety application should be thoroughly tested before it is deployed in a real world to use. Simulator tool has been preferred over out door experiment because it simple, easy and cheap. VANET requires that a traffic and network simulator should be used together to perform this test. Many tools exist for this purpose but most of them have the problem with the proper interaction. S...

In this paper, we characterize the performance of parallel $le transfers using the Zebra Striped Network File System by means of distributed discreteevent simulation model which uses a variation of the conservative timestamping technique. The simulator is a powerful tool that can be adapted to model related systems such as multiprocessors and distributed shared memory. Preliminary simulation re...

Thomas Fuerle and Erich Schikuta Institute of Applied Computer Science and Information Systems, University of Vienna, Rathausstr. 19/4, A-1010, Vienna, Austria Email: [email protected], [email protected] Abstract This paper describes the speci cation and implementation of PANNS (Parallel Arti cial Neural Network Simulator), a general purpose tool for building, running and ana...

In this work we present a prototype for simulating computer network attacks. Our objective is to simulate large networks (thousands of hosts, with applications and vulnerabilities) while remaining realistic from the attacker’s point of view. The foundation for the simulator is a model of computer intrusions, based on the analysis of real world attacks. In particular we show how to interpret vul...

Ad Hoc networks are characterized by fast dynamic changes in the topology of the network. Introduction of new routing algorithms requires a deep and trustworthy evaluation process. In this paper we describe an Interactive Flexible Ad Hoc Simulator (IFAS) that presents a modern and novel approach to the family of Ad Hoc simulators. This simulator supports unique viewing, debugging, tuning and in...
