OMNeT++ is an extensible, modular, component-based C++ simulation library and framework, primarily for building network simulators.
Castalia 3.0 released
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
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.
New Releases: INET-20100723, R package 0.2
We are happy to announce a new release of the INET Framework with many improvements to TCP and other components (What's New), and a new version of the package for processing OMNeT++ result files with GNU R. Downloads: INET-20100723, "omnetpp" R package.
PhoenixSim: A Simulator for Photonic Interconnection Networks
PhoenixSim 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
The MiXiM team is happy to announce the release of MiXiM 1.2 that uses OMNeT++ 4.1. 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 release contains the IEEE 802.15.4 models developed by Jérôme
Rousselot; IDE wizards to create basic MiXiM networks and your own analogue models; extensive documentation update and additions; and many bug fixes and enhancements. An overview of the most
important changes is given after the Read more link. Developers should pay special attention
to some API changes outlined below! For a complete list of changes, please
consult the git log messages. The new MiXiM release can be downloaded from the project's site at SourceForge:
