Next talks



"User-centric Cloud-Based Architecture," II EU-Brazil Cooperation Workshop in ICT - EUBR 2014, together with SBC 2014. July 29th, 2014, at Brasilia

The way that users communicate these days is very different from a few years back. The classic host-based paradigm, in which users would make requests for specific content stored in specific locations, is giving room to new forms for users to exchange data. This is a product of not only devices becoming very portable, but also gathering the latest advancements in terms of processing, storage, and wireless technologies. Thus, users are able to produce and consume content anywhere and anytime, and such data exchange may take place through spontaneously formed networks. Furthermore, this content can be store locally and/or on the users' personal clouds, as well as on public clouds. Different networking approaches (e.g., Delay/Disruption-Tolerant Networking, Opportunistic Networking, Information-Centric Networking, User-Centric Networking) have emerged and have been able to deal with the different challenges (e.g., intermittent connectivity, high mobility, longer delays, expensive infrastructure and/or connectivity). Also, Cloud and Big Data systems should be integrated to these networking approaches as they can further increase the capabilities of the user devices and handle the vast amount that users produce. In this talk we present our vision and proposal for a integrative, clean slate architecture, which fits the Brazil-Europe Cloud+Security Horizon 2020 call requirements and includes a set of novelties beyond current state-of-the-art.


"Internet do Futuro," Cidade Feliz, Cidade Criativa. August 12th, 2014, at Santa Rita do Sapucaí.

Is it possible to design a new Internet? What could be the benefits? How it could be? Introducing NovaGenesis future ICT architecture.







The Internet has invaded most aspects of life and society, changing our lifestyle, work, communication and social interaction and giving us expectations about new forms of interactions and access to global knowledge. Application and user demands on the Internet are increasing with mobile technologies and media content. Nevertheless, the Internet today is a complex agglomerate of protocols that inherits the grown legacies of decades of patchwork solutions.There is a common consensus that the current Internet needs improvement. Nevertheless, there is not yet a shared vision on how this may happen. As a direct consequence research pro- grams have started worldwide to re-think traditional Internet design principles and to come up with new architectural concepts for the so-called Future Internet (FI). The FI has certainly a more broad scope than the current one, since it needs to integrate recent advances on Cloud Computing, Software-Defined Everything (radio, networks, systems, etc), Internet of Things, Service-Oriented Architectures, Content-Distribution Networks, Autonomic and Cognitive Networks, and so on. This tutorial gives an introduction to Future ICT, focused on correlating several emerging technologies. It summarizes perspectives and already identified requirements, challenges, and trends behind key technologies that can be used on this task. More specifically, it covers substrate resources (computing, communications, etc) capacity, scalability, ubiquity, exposition, and virtualization; Internet of Things (IoT) and Real-World Internet (RWI) approaches; In- formation-centrism; the role of naming in design, the paradigm of identifier/locator splitting; the role of semantic and context, specially for autonomic and cognitive architectures; mobility, security, privacy, trust; and Software-Defined Everything. The ideas of Internet of Services (IoS) and Service-Based Applications (SBA) are discussed. It discusses simplicity, sustainability and evolvability of design, as well as how to accommodate tussles, regulations, policies, etc. Finally, it briefly presents NovaGenesis future ICT architecture, given an overview of the proposed design, as well as discussing its integration with Cognitive Radio over Fiber Networks, IoT, and user-centric architectures.




The Internet is an amazing artifact of human ingenuity. It has invaded most aspects of life and society, changing our lifestyle, work, communication, and social interaction. Nevertheless, the Internet nowadays is a complex agglomerate of protocols that inherits the grown legacies of decades of patchwork solutions. Protocols were added to extend the architecture towards new usages. Limitations on naming, security, scalability, mobility, and routing support - to name a few of them - are increasingly concerning Internet professionals and researchers. This reality check has been motivating many people to ask whether is it possible to redesign the Internet? Since this question was first made, several initiatives to reshape the Internet appeared all around the world under the banner of the so called Future Internet Architecture (FIA) design. In this talk, I am going to provide a panorama on the current Internet state, briefly presenting and discussing some of its main limitations and problems. Continuing, I am going to present very briefly some clean slate (tabula rasa) FIAs, including the one we are proposing: the NovaGenesis information architecture. To conclude, I will give some details of the tests I did together with ETRI - Electronics and Telecommunications Research Institute during my post-doc in South Korea.

Among these initiatives, there is the NovaGenesis universal convergent information architecture, which can be seen as a new architecture to replace the current Internet TCP/IP.


The talk presents the general idea of ​​IoT and the work that has been done at Inatel so far. Discusses the current state of IoT solutions, pointing out several aspects that still need to be improved. After, discusses solutions that no longer depends on TCP/IP, especially presenting a proposal called NovaGenesis, which is being developed at  Inatel since 2008.
