“…In the future, we expect that it will be possible to implement HRSON on real smartphones. For this purpose, we should consider existing middle-wares such as ShAir [15] and Haggle [16]. In the latter, the devices can connect through available infrastructures, cellular network or opportunistic network, according to their conditions and their need.…”

Opportunistic networks are delay-tolerant networks which enable network connectivity while there is limited access to network infrastructure, such as natural disaster happenings. Since opportunistic networks use storecarry-forward mechanism to deliver data, routing algorithms have significant impact on successful data delivery. Due to the Operating System restrictions, creating an opportunistic network using ad-hoc model is not feasible on smartphones and to the best of our knowledge, none of common zero-knowledge routing algorithms have been proposed for a non-ad hoc communication model. In this paper, we propose HRSON, a zero-knowledge routing algorithm in a self-organizing approach that an opportunistic infrastructure-based WiFi network is built to use smartphones. We have deployed our approach in simulated scenario of working days of people, whom are using smartphones, on Helsinki map comparing to common zeroknowledge routing algorithms. The results show that our solution increases the average delivery-rate and lowers delay and commutation overhead.

“…However, by creating a WiFi access point and letting other devices join the created network, effectively, device-to-device communication can be implemented in this mode. With ShAir, a middleware with this approach is presented in [36]. Furthermore, popular file sharing applications use this approach, for example the app Xender 6 .…”

Recommender systems recommend new movies, music, restaurants, etc. Typically, service providers organize such systems in a centralized way, holding all the data. Biases in the recommender systems are not transparent to the user and lock-in effects might make it inconvenient for the user to switch providers. In this paper, we present the concept, design, and implementation of MobRec, a mobile platform that decentralizes the data collection, data storage, and recommendation process. MobRec's architecture does not need any backend and solely consists of the users' smartphones, which already contain the users' preferences and ratings. Being in proximity in public places or public transportation, data is exchanged in a device-to-device manner, building local databases that can recommend new items. One of biggest challenges of such a system is the implementation of unobtrusive device-to-device data exchange on off-the-shelf Android devices and iPhones. MobRec facilitates such data exchange, building on Google Nearby Messages with Bluetooth Low Energy. We achieve the successful exchange of data within 3 to 4 minutes, making it suitable for the described scenario. We demonstrate the feasibility of decentralized recommender systems and provide blueprints for the development of seamless multi-platform device-to-device communication.

“…Com o objetivo de permitir comunicação D2D em cenários no qual não há acessoà Internet, outras abordagens [22,23,15] com uma Arquitetura descentralizada foram desenvolvidas. Essas abordagens utilizam Tecnologias de Rede Sem Fio como o Bluetooth para estabelecerem a comunicação D2D e realizarem a troca de conteúdos.…”

Mobile devices and the cellular network have been popularized and evolving in recent years. The increase of these devices may promote Device-to-Device (D2D) communications. However, current D2D communication technologies such as Wi-Fi Direct, Wi-Fi Ad Hoc, and Bluetooth are not available on devices or require human interaction in the pairing process. In addition, the cellular network is not available in many places and has partial or total communication infrastructure failures. To overcome this failure and lack of connectivity, and to allow D2D communication between devices in disturbing scenarios, we presented CoWPar. Based on the Wi-Fi infrastructure mode, CoWPar establishes the connection and performs data exchange without human interaction between the devices. Results of experiments performed in a proof of concept showed in practice that CoWPar allowed D2D communications with no pairing and also without the need to change the operating system (OS) of the devices, surpassing all the works available so far and thus contributing to the process of viabilization the paradigm of Pervasive Computing.
