    Counting time in drops : views on the role and importance of smartwatches in dew computing.
    (2019) Garrocho, Charles Tim Batista; Oliveira, Ricardo Augusto Rabelo
    A large amount of data, called the big data, generated by the devices that are part of the Internet of Things, is expected in the coming years. This scenario creates challenges for sending, processing, and storing all data centrally in the cloud. Recent works propose a decentralization of the processing and storage of this data in local devices close to the user to solve such challenges. This paradigm, called dew computing, has been gaining attention from academia. Several works apply this proposal through devices such as desktops, laptops, and smartphones. However, after a systematic review, no studies were found that applied this proposal to smart wearable devices. Thus, this work shows the research, evaluation, analysis, and discussion of smartwatches for the dew computing environment. The results of this work showed that smartwatches could extend local device functionalities through performing services, cooperating with decentralizing cloud computing, and helping to reduce the negative impacts of the big data.

    D2D pervasive communication system with out-of-band control autonomous to 5G networks.
    (2018) Garrocho, Charles Tim Batista; Silva, Maurício José da; Oliveira, Ricardo Augusto Rabelo
    D2D (device-to-device) communication is one of the developments of 5G networks (5th generation mobile networks) that reduce mobile traffic load, reduce energy consumption and effectively use the available electrical radio spectrum. An increase in the number of mobile devices might, in theory, promote D2D communications to 5G networks; however, in practice, the D2D communications technologies, such as Wi-Fi Ad-Hoc, Bluetooth and Wi-Fi Direct, are not available or require human interaction. To overcome these limitations, a middleware based on Wi-Fi infrastructure mode, which establishes connections and performs data exchange without human interaction, is presented. Practical proofs of the concept demonstrate that the middleware enables transparent D2D communications for 5G applications.
