Welcome to the OMNeT++ Community!

OMNeT++ is an extensible, modular, component-based C++ simulation library and framework, primarily for building network simulators. "Network" is meant in a broader sense that includes wired and wireless communication networks, on-chip networks, queueing networks, and so on. Domain-specific functionality such as support for sensor networks, wireless ad-hoc networks, Internet protocols, performance modeling, photonic networks, etc., is provided by model frameworks, developed as independent projects. OMNeT++ offers an Eclipse-based IDE, a graphical runtime environment, and a host of other tools. There are extensions for real-time simulation, network emulation, alternative programming languages (Java, C#), database integration, SystemC integration, and several other functions.

OMNeT++ is free for academic and non-profit use, and it is a widely used platform in the global scientific community. Commercial users must obtain a license from omnest.com. More...

MiXiM 2.0 Released, Contains Support for INET Integration
Wednesday, 20 October 2010 00:00

The MiXiM team has released MiXiM 2.0. The main highlight of this release is MiXiM - INET Framework integration. MiXiM 2.0 contains a "Mixnet" example simulation that demonstrates how one can use MiXiM network interface cards (NICs) together with higher layer protocols (IP, TCP, UDP) of the INET Framework. MiXiM provides the necessary modules to make the two frameworks compatible, as well as documentation and examples how to build simulations using both frameworks. The new release also fixes some bugs and contains small interface changes. An overview of the most important changes is given after the break.

MiXiM is an OMNeT++ modeling framework created for mobile and fixed wireless networks (wireless sensor networks, body area networks, ad hoc networks, vehicular networks, etc.). It offers detailed models of radio wave propagation, interference estimation, radio transceiver power consumption and wireless MAC protocols.

The new MiXiM release can be downloaded from sourceforge.net. In order to use MiXiM together with INET, an INET version without the wireless-related classes is needed, which can be downloaded from here.

Simple Obstacle Model for INET and MiXiM
Tuesday, 28 September 2010 12:35
From Christoph Sommer: We've now prepared and uploaded the codebase of our "Computationally Inexpensive Empirical Model of IEEE 802.11p Radio Shadowing in Urban Environments" for public consumption. The obstacle model lives at http://www7.informatik.uni-erlangen.de/~sommer/omnet/obstacles/, and can be downloaded for both the INET Framework and for MiXiM. The code is GPL-licensed, so feel free to integrate it with any compatible framework. An in-depth documentation of the model, as well as the results of extensive experiments we performed using IEEE 802.11p radios mounted in cars can be found in the Technical Report of the same name, published at http://www7.informatik.uni-erlangen.de/~dressler/bib/inc/sommer2010computationally-abstract.shtml. If you have any questions, don't hesitate to get back to me!
 
Castalia 3.0 released
Thursday, 12 August 2010 00:00

From the Castalia team: Castalia 3.0 is finally here! It runs with OMNeT 4.x and it offers a complete new way to run simulations and view the results. It has a brand new radio module. It implements the Baseline MAC for Body Area Networks, proposed by the IEEE 802.15 Task Group 6. Read the new User's Manual to get started! The new release can be downloaded from the Castalia home page.

Castalia is a simulator for wireless sensor networks (WSNs), body area networks (BANs), and generally networks of low-power embedded devices; it is developed at NICTA Australia.

 
Google Earth Demo
Friday, 23 July 2010 07:35
We have created a demo about visualizing a simulation on Google Earth. The demo will be part of OMNeT++ 4.2, and for now there is a separate download so you can try it before 4.2 arrives. We have also recorded a video about it. The demo simulates a wireless mobile ad-hoc network, where cars move about randomly over a 2km-by-2km area. They have identical radios, with a transmission range of about 500m; for simplicity, we assume that the area covered by each radio is a perfect circle. When two modes move within range of each other, they can communicate with each other, forming a (usually disconnected) ad-hoc network. The purpose of the simulation study could be to measure how long it takes to disseminate some piece of information to all nodes of the network. The communication itself is not modeled in this demo. Visualization shows the mobile nodes themselves (a 3D car model), their recent trails, their transmission ranges, and the current connectivity of the network.

PhoenixSim: A Simulator for Photonic Interconnection Networks
Friday, 09 July 2010 11:53

4x4 switchPhoenixSim is an OMNeT++-based simulation environment being developed by the Lightwave Research Laboratory at Columbia University in the City of New York for designing and analyzing the performance of photonic interconnection networks. PhoenixSim enables detailed studies of electronic networks, photonic networks, and hybrid networks (ones that leverage a combination of both technology domains). The simulator is highly extensible and is currently being used within the Lightwave Research Laboratory on projects for the design of on- and off-chip photonic communications for multi-processor systems, and the design of nanophotonic optical broadband switches (NOBS).

Currently, the simulator supports the ability to model and characterize many important properties of photonic interconnection networks including propagation delay, insertion loss, extinction ratio, spectral resonant profiles, area occupation, and energy dissipation. Moreover, future extensions will support the modeling of thermal variations, optical nonlinearities, as well as three-dimensional integration. In the realm of electronics, the simulator includes a router model that can be used to model advanced electronic networks and hybrid networks.

Network Simulation Book Featuring OMNeT++
Monday, 05 July 2010 19:49
"Modeling and Tools for Network Simulation" (Klaus Wehrle, Mesut Günes, James Gross [Editors], Springer, 2010) is a book that focuses on tools, modeling principles and state-of-the art models for discrete-event based network simulations. The focus of the "tools" part is on two distinct simulations engines: OMNeT++ and ns-3, where the OMNeT++ chapter presents a high-level overview and rationale of the concepts, techniques and tools present in that simulation environment. The book also deals with issues like parallelization, software integration and hardware simulations. In the "modeling" part of the book, the wireless section covers all essential modeling principles for dealing with physical layer, link layer and wireless channel behavior, and presents detailed models for IEEE 802.11, IEEE 802.16 and other systems. Further chapters cover classical modeling approaches for higher layers (network layer, transport layer and application layer) and modeling approaches for peer-to-peer networks and topologies of networks.

See the book's page at RWTH Aachen or at Springer (with table of contents), or buy it from Amazon. (Note that the book's length is misprinted on those sites -- it's actually 500+ pages not 256.)
