Problem to address:
Video is becoming the most used type of traffic on the Internet, especially used by mobile terminals in wireless environments. It is important to develop the necessary Internet framework mechanisms, deployable by operators, to allow users to enjoy video with a greater Quality of Experience in the coming years. It is important to allow video traffic to be adjusted based on the characteristics of the terminal and the network, as well as based on the requirements of the user and the video itself.

Project contributions:
The project provided a number of novel solutions, contributing to numerous fields. Of note, and featuring the active contribution of the ATNoG group, the project contributed to: IP mobility management protocols, multicast routing and mobility, media independent handovers, access technology-independent control and optimisations, energy-efficiency, wireless transport enhancements (jumbo frames), amongst others. ATNoG was able to provide not only conceptual architectural evolutions, but also to deploy its own open-source software, in the form of ODTONE ( and OPMIP (

Project Description

This 7th Framework Programme for Research and Technological Development Specific Targeted Research Projects has the main goal of evolving the mobile Internet architecture for efficient video traffic support. In the near future, it is expected that video traffic will represent the majority of traffic in the near future, requiring that the underlying infrastructure supports the requirements of this kind of traffic, as well as featuring enhancements on all layers of the protocol stack.

MEDIEVAL will set its stand on mobile heterogeneous networks, which represents a challenging communication environment and the one that will be most affected by video as a widespread communication medium. In MEDIEVAL we will develop the technologies that will provide low cost access to video entertainment anytime, anywhere, boosting social networks with multimedia communications. It is the project's vision, mobile video is as simple and cheap to use as current voice and SMS communications.
Key Concepts

  • Coordination between video services and the underlying network services through a new MEDIEVAL interface.
  • Exploitation of wireless access technologies in coordination with the video services to optimized video performance under these environments.
  • Adaptation of next generation mobile networks to video services through a comprehensive mobility architecture
  • Optimization of the video transport itself by means of increased QoE, through the use of network support of caching and P2P video streaming.
  • Introduction of multicast mechanisms at different layers to better support broadcast and multicast video services
