Current Research Projects and Collaborations

  • On supporting Ambient Assisted Living applications through Named-Data Networking and Internet of Things. Among the proposals for new Internet architectures, NDN is the one that has presented the most significant advances and has strong support from industry and academia. Its properties are the ones that most address the requirements of AAL applications, characterized by the use of IoT devices, intense mobility, and communication between different devices. Therefore, this project aims to investigate how the NDN architecture associated with IoT can meet AAL systems requirements and boost the development of AAL applications. When using NDN to support AAL applications, it is crucial to identify and define naming schemes, forwarding models, routing protocols, and security strategies to meet the requirements specified in the scenarios. The expressive semantics of the name, the dynamic definition of forwarding strategies, the development of lightweight routing protocols, and a flexible trust policy characterization can contribute to these goals. Partners : Universidade Federal da Bahia (UFBA) and University of California at Irvine (UCI)

  • On Supporting the Internet of Things Through Named Data Networking: Interoperability, security, and mobility. Despite the benefits and potential of the NDN architectures to meet the challenges of communication among network devices in IoT, many R&D issues are still open and in the early stages of discussion. Thus, the main goal of this research is to define and implement architectural elements of NDN that provide native support for the communication of devices in the Internet of Things for interoperability, mobility and security. This general objective results in the following specific objectives: (i) the development of confidentiality and integrity mechanisms for network contents; and (ii) support for the mobility of data producing and consuming nodes; (iii) the definition of an adaptation layer that supports multiple link leveltransmission technologies. Universidade Federal da Bahia (UFBA) and University of California at Lost Angele (UCLA)

  • Human and Context-Awareness as Mobility Support in Information-Centric Networks. The project consists of a proposal of an international cooperation whose main objective is to identify new strategies that contribute to the offloading of data in mobile information centric networks. Partners : Universidade Federal da Bahia (UFBA) and Institut National de Recherche en Informatique et en Automatique (INRIA)

  • CREDENCE: Collaboration Network for Excellent Education and Research in Dependable and Secure Distributed Systems . CREDENCE addresses all aspects of BBChain as well as distributed systems more broadly, with partner expertise in publish/subscribe, high-performance computing and socio-technical aspects. In particular, the proposed collaboration will strengthen the BBChain project by advancing the state-of-the-art in designing, evaluating and validating exploit sensitive blockchain infrastructures, including those used for cryptocurrencies, biometrics-based document storage and high volume data streams that require integrity protection.

  • BAMBU - A Metropolitan Innovation Testbed for Promoting Future Internet Research in Salvador city (Project presentation). Its main goal is to design and implement a metropolitan innovation testbed for promoting practical Future Internet research in the city of Salvador, Bahia. Partners: Universidade Federal da Bahia (UFBA), Instituto Federal da Bahia (IFBA), Centro de Pesquisa Gonçalo Moniz – Bahia (Fiocruz-Ba), Rede Nacional de Ensino e Pesquisa (RNP), Universidade Federal do Espírito Santo (UFES), Laboratório Nacional de Computação Científica (LNCC), Florida International University (FIU), and Phillips Research North America.
