Open Source Java Simulation Software

ABSim is an Agent-Object-Relationship (AOR) simulation system based on a Java program library. The development of ABSim has terminated. Its successor is <a href="http://oxygen.informatik.tu-cottbus.de/aor/?q=node/2">AOR-JSim </a>

GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching geometry, algebra, statistics, and calculus. Download the free software at http://www.geogebra.org. Find the source code at http://www.geogebra.org/trac

Discontinued.

JCPUSim is a CPU (Central Processing Unit) simulator written in Java. It is intended to aid in teaching how the fetch-decode-execute cycle, CPU, registers, memory and assembly programming language work in a computer system.

Paean is a tool to demonstrate in real-time the effect of various error-correcting codes on data transmitted via several channel models.

Ceci est le projet réalisé à la session d’hiver 2014 par l’équipe Expresso. L’équipe était composée de : Philippe Olivier, François Lemonnier-Lalonde, Dominique Tremblay et François Moreau. Le projet a été réalisé pour le cours de Génie logiciel orienté objet, donné par M. Jonathan Gaudreault à l'Université Laval. Le projet consistait à développer un logiciel de modélisation de réseau de files d’attente, aussi appelé un réseau de Jackson. Chaque nœud du réspeau représente une station de traitement et chaque arc orienté représente un chemin possible d’une station à une autre. Le réseau possède toujours un point d’arrivée et de sortie. Un tel réseau peut, par exemple, représenter la zone de sécurité d’un aéroport, l’urgence d’un hôpital ou une chaîne de montage.

A wireless push-type network simulator that considers locality of demand for performance improvement. The network environment consists of multiple directed emitters for parallel data broadcasting. Performance depends on the mean response time of clients.

RangeSim is a collection of classes for simulating distributed protocols for range search on P2P (peer-to-peer) network environments. It is based upon the PeerSim simulator, which offers easy configuration, extendability and high performance.

java-turing-emulator aims to provide a GUI for creating, editing and simulating Turing machines and deterministic machines. its build in java and uses the swt-framework.

Multimedia consumption at social events - if available - can be considered as a complex problem. People use their smart phones and tablets to take pictures and videos, leading to a high number of production places. If we enable those visitors to share their content at the event, new challenges emerge. Visitors move, go online and offline, and build a dynamic network. One can say a complex adaptive network emerges, with all its problems. We tackle these problems by introducing a bio-inspired algorithm, which lets the content place itself where it is needed. It is robust, scalable and adaptive. The transport path of content is exploited to replicate content and limited storage space is handled by clean-up mechanisms. We implemented a simulator to show the algorithm's performance and to test its behavior under real circumstances. It is easily extendable to support several new scenarios or changes to the algorithm (see replication and client models).
