Welcome to OPEN DOT TWENTY ONE - An open-source multiple-plaftorm IEEE 802.21 MIHF implementation

ODTONE stands for Open Dot Twenty ONE and is an Open Source implementation of the Media Independent Handover framework from the IEEE 802.21 Media Independent Handover Services standard, using C++ APIs.

Latest NEWS:

Our next ODTONE release (v0.3) will add important bugfixes and features, such
as the MIH Sensor SAP, which brings the world of Media Independent
Services to Wireless Sensor Networks! Stay tuned for more.

What is ODTONE?

ODTONE supplies the implementation of a MIHF, supporting its inherent services (Media Independent Event Service (MIES), Media Independent Command Service (MIIS) and Media Independent Command Service (MICS), as well as supporting mechanisms (Capability Discovery, MIHF Registration, Event Registration, etc.). It also provides a set of APIs to enable ODTONE users to implement their own MIH-Users and LINK_SAP and interface with ODTONE's MIHF.

What differences can be found regarding other IEEE 802.21 implementations?

ODTONE aims to implement a MIHF that is capable of being deployed in multiple operating systems. In a first stage, it will support GNU/Linux, followed by Microsoft NT-based operating systems and others. This means this implementation will be decoupled of highly dependent operating system mechanisms.

What does this mean?

ODTONE's implementation aims to provide a MIHF that will work as a base for user's scenarios, and which will enable the users to implement their own MIH_SAP and MIH_LINK_SAP. ODTONE will provide a simple and flexible interface for the development of these SAPs, handling MIH Protocol messages and state transitions.

How can I contribute?

As was previously mentioned, ODTONE will focus on the MIHF and API's that will enable users to implement their own MIH_SAP and MIH_LINK_SAP. This means that it will be entirely up to the user to implement their MIH_USER and LINK technology support. After we release the code, we would be more than happy to know about your work on these matters!

* ODTONE BETA version RELEASED! Now, with the Media Indepentent Information Service and a LGPL software licence. Please go to: http://helios.av.it.pt/projects/odtone for more info and code download.

* The ODTONE's MIHF implementation is getting closer and closer to launch. In some weeks, we will have remote messaging capabilities fully implemented and will be able to make the code available.

* IT Aveiro participated in the ETSI FMCA Seamless Mobility Interop Event, in Sophia-Antipolis, France, where IEEE 802.21 interoperability was tested amongst different implementations. ODTONE was presented in the event, raising awareness and interest as the only multi-platform open-source MIHF implementation.
