The 1st International OMNeT++ Developers Workshop was held on March 7, 2008 in Marseille, France, with the purpose of bringing together OMNeT++ users and their tools, applications and ideas. Although there were OMNeT++ workshops before, this was the first peer-reviewed workshop, associated with a main conference (SIMUTools 2008). It was a successful workshop, with a number of high-quality papers (12) and posters (8) presented (chosen from above 30 submissions), with the number of workshop participants being above 40. You'll find more information and also photos in the Concluding Remarks here (pdf link).

A collection of links to the PDF versions of papers, slides and associated software is available on this Wiki page. If you are a workshop author, you are welcome to expand the page with more links (to slides, related project web pages, etc).

SimProcTC is a model-independent, flexible and powerful tool-chain for the setup, parallel run execution, results aggregation, data analysis and debugging of OMNeT++-based simulations, using Open Source software under Linux. It optionally utilizes the Reliable Server Pooling (RSerPool) implementation RSPLIB for easily setting up simulation processing pools for distributed execution of simulation runs. Compared to other approaches like Akaroa, this RSerPool-based solution requires minimal configuration effort due to fully automatic configuration of the components. SimProcTC was developed by Thomas Dreibholz at the Institute for Experimental Mathematics, University of Duisburg-Essen.

• Cooperative pull based content management policy.
• Non-Cooperative pull based content management policy.
• LRU cache replacement policy.
• STATIC cache policy.
• TCP / IP networking.
• Wizard for creating self-contained simulations (bottles).
• Utility for executing unattended simulations.
• Utility for automatically generating results' reports.
• Utility for converting Apache log files into CDNsim trace files.
• Extensible by implementing modules in the form of libraries.
• Runs on Windows and Unix like systems.

Documentation, publications, source code and screenshot(s) can be found at the CDNSim home page.

The Castalia Team has released the 1.3 version of their OMNeT++-based Wireless Sensor Network (WSN) simulator. Improvements over version 1.2 include:

• Implementation of 2 routing protocols
• Implementation of 2 new example applications (using routing protocols)
• Advanced ability to define various degrees of simpler channel and radio models
• Bug fixes with the TunableMAC and routing modules

U2Q is a tool developed by Lukas Pustina at University Bonn. U2Q allows developers to estimate the performance of a system prior to prototypes, based on UML models only.

The tool implements a design methodology that allows developers to estimate the performance of a system in very early stages of development where no prototypes are yet available. Starting from a functional UML system model, the developer enhances the system model by incorporating performance annotations. From this performance aspects enhanced system model, U2Q generates Queueing Networks as performance models which then may be analysed using analytical or simulative approaches. The tool itself smoothly integrates into Telelogic Tau G2 3.1 and brings a command line version.

Documentation, screenshots and code is available from the web site.

ACID Sim Tools is an interactive and batch-mode simulation tool (and framework) developed by Anakreon Mentis, Panagiotis Katsaros and Lefteris Angelis at the Aristotle University of Thessaloniki for the performance evaluation of different combinations of concurrency control, atomic commit processing and recovery protocols (and protocol parameters), based on a minimal set of assumptions for an object-based computational model. The tool produces metrics that provide insight into the most influential performance and availability trade-offs that arise in distributed transaction processing architectures. Documentation and source code is available at their ACID web site.

The simulator will also be presented at SimulationWorks 2008 conference, which is co-located with the Simutools 2008 conference and the OMNeT++ 2008 workshop.

An updated version of the InfiniBand model can be downloaded from here. It incorporates the patch posted to the mailing list on Jan 18.

The simulation community has been accused for producing many simulation studies of bad quality. The mission of the oProbe open source project is to provide an instrument that produces statistically sound results at known quality. Stochastic sampling from a network of queues demands both confidence and correlation control. An important design goal is to be compatible with the OMNeT++ framework without introducing changes to this code, as well as making it easy for existing simulators to make use of oProbe. The oProbe project introduces a probe module, which is a new simple module in the context of OMNeT++. A probe is the instrument that applies a controlled stochastic sampling technique. The probe module may have any number of probes. The oProbe project supports different interface levels according to the functionality required. Based on the FIFO queue example included in the sample directory in OMNeT++, the oProbe project provides example code on how the software can be used by existing or upcoming OMNeT++ based simulators.

Last year we have activated several projects In my research group
1. A new MAC protocol for ad hoc networks
2. An IEEE 802.16-2004 and IEEE-802.16 e compliant simulation modules for both SS and BS.
This year we continue with
1. developing the routing layer for wireless ad-hoc networks that will make an efficient use of our MAC protocol
2. construct a research on resource allocation for MESH networks under the IEEE-802.16 E standard
Another research group is using OMNET++ to simulate the activities of network processors in high speed networks

From  Felix Hoffmann:

The Institute of Communications and Navigations at the German Aerospace Center (DLR) is currently developing a simulation platform for aeronautical communications within the project FACTS - Future Aeronautical Communications Traffic Simulator. The project investigates the possibilities of shifting from voice communications to digital data traffic in Air Traffic Control, and creating an IP-based aeronautical telecommunications network. The simulator is based on OMNeT++ and the INET Framework, and will feature a NASA WorldWind-based GUI.
