- New application layer multicast protocol NICE
- GNP/NPS network coordinate system
- Hotspot roaming model for simplegameclient
- DHT: support for multiple entries with the same key

Castalia 2.2 was released on 14-8-2009. It implements most core features of the IEEE 802.15.4 MAC protocol that are relevant to Body Area Networks (i.e.,
single hop PANs with coordinator and beacons). Castalia 2.2 is a simulator for wireless sensor networks (WSNs), and it requires OMNeT++ 3.x. |

Do we know about your papers? |
|
Saturday, 15 August 2009 20:22 |
As you may have noticed, we have recently expanded our Publications database. First of all, it should now contain nearly all OMNeT++-related papers, from the beginnings until a few months ago -- presently over 400 entries! The database can be searched and filtered by words that occur in the title, authors, keywords, year, or abstract (yes, we store the abstracts as well, for better search results!). We have also added convenient "Web link" and "Search web for title" functions, so that you can find a copy and start reading as fast as possible. Entries are stored (and can exported) in BibTeX format.
Please help us make this database a useful reference! Check if it contains your papers, and if not, submit them. We are mostly interested in last years and earlier papers, because we'll periodically add the new ones by skimming various online databases anyway. |

Announcement: oTWLAN – a tool to simulate tactical ad-hoc networks |
|
Friday, 17 July 2009 12:51 |
|
oTWLAN models a wireless ad-hoc network, which supports multi-level
precedence and preemption (MLPP) over a DSSS radio. This open source project
facilitates throughput/delay performance study through a GUI based user
interface. oTWLAN has many
similar characteristics to WLAN (IEEE 802.11) but also provides a 100kbps radio
channel for enlarged radio coverage, relaying of traffic for increased service
coverage area and priority handling of user traffic. The latter is especially
important for military and emergency network. The simulator has been developed
within the GOSIKT project at the Norwegian Defence Research Establishment where
we study the performance of PKI over tactical ad-hoc networks. Chapter 2 in the
user manual included in this open source project illustrates the usage of the
simulator while other chapters describe the network protocols implemented.
Later versions of this project will be published on
http://sourceforge.net/projects/otwlan/ |

Announcement: Energy Framework 0.9 |
|
Friday, 17 July 2009 08:24 |
The Communication Networks and Systems Lab at SICS is happy to announce version 0.9 of the Energy Framework.
The Energy Framework is a collection of modules that allows flexible and extensible modeling of battery consumption of wireless devices. It currently uses OMNET++-3 and mobility-fw2.0p3,but is intended to be relatively framework independent. Code is available at http://www.sics.se/nets/software.

SZTAKI Grid Portal for Simulations |
|
Tuesday, 14 July 2009 09:36 |
The GASuC team at the Laboratory of Parallel and Distributed System (LPDS), MTA SZTAKI has announced public access to a computing grid for OMNeT++ simulations. The grid can be accessed via a Web portal, and currently lets users submit and run pure
INET Framework and Queueinglib simulations on a 10-CPU grid architecture. (Further grid nodes will be added as needed.)
The LPDS team is inviting you to try and run simulations on the grid! Feedback is welcome.
Grid portal address: https://pgrade-omnet.sztaki.hu (scroll down for login)

Announcement: MiXiM 1.0 released |
|
Tuesday, 23 June 2009 20:46 |
The MiXiM team is happy to announce the first official MiXiM release, MiXiM 1.0. MiXiM is an attempt to merge several OMNeT++ simulators written to support mobile and wireless simulations. This release contains only the parts of MiXiM which we considered tested and stable enough for release. These are:
- a base model for a detailed wireless physical layer
- analogue model implementations for "Jakes fading", "Lognormal shadowing" as well as a simple path loss model
- a CSMA Mac layer and a 802.11 Mac layer
- mobility pattern modules known from the Mobility Framework (like Tractor-, Turtle- and CircleMobility)
MiXiM can be downloaded from the project's Sourceforge download area, or can be checked out directly from the git repository at git://mixim.git.sourceforge.net/gitroot/mixim.
Still in development are implementations of a S- and T-Mac protocols. You can find the parts which are still in development in the git repository's "development" branch. Also, Jérôme Rousselot has written a MiXiM branch which contains a detailed model of an UWB physical layer; it can be found on github as the mixim-uwb project.

Welcome to the new OMNeT++ Community Website |
|
Friday, 22 May 2009 13:51 |
Dear OMNeT++ Users,
Welcome to the new, redesigned OMNeT++ community site. The old, Geeklog-based website infrastructure has served us in the last 6 years, but its age has started to show, and had to be replaced. The new website is based on Joomla, and we hope it will solve all our previous problems. A few things you should now:
- We have removed all the unused services. Calendars, polls, Web links are gone.
- The forum was also dropped, as it was mostly a write-only medium, and the new mailing list will double as a forum too.
- The content of the site is mostly the same (we converted almost all content), but we have reorganized the site navigation a bit.
- A bibtex-based Publication Database was added for keeping track of OMNeT++ related papers. We made a good effort to collect publications from several online libraries and collections, but we don't know about the coverage. Please help us getting up-to-date by checking that it contains all your publications! You can submit the missing ones via a web form.
- A Model Catalog was added to gather all OMNeT++ models in a single place.
- User accounts were not taken over from the old site. Please re-register on the new site if you wish.
- We moved the mailing list to Google Groups. This allows you to follow the discussion via XML feeds, write to the group from the web directly, browse and search the archive in threaded mode. We have moved the old member list, however if you have recently subscribed to the omnetpp list, you may have to re-subscribe. The mailing list's address has changed, but the old list address still forwards to the new e-mail address. We are sorry for any inconvenience.
- As a registered user, you will be able to submit news items, new models and publications.

Castalia 2.0 (for OMNeT++ 3.x) has been released. Castalia is a
simulator for Wireless Sensor Networks (WSN), Body Area Networks (BAN),
and generally networks of low-power embedded devices. It offers an
advanced channel model based on empirical measurements that supports
mobility and temporal variability. It also offers many features that
are often neglected in network-level simulation, such as realistic
radio modeling and access, node clock drift, and physical process
modeling. Castalia is an expandable, modular and user-friendly
simulator with a growing research community. For more info go to http://castalia.npc.nicta.com.au. |
