    Mobile Computing in Digital Ecosystems: Design Issues and Challenges

    Full text link
    In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the construction of what we term a digital ecosystem, i.e., an ecosystem constructed out of so-called digital organisms (see below), that can foster the development of novel distributed services. In this context, a human user equipped with his/her own mobile devices, can be though of as a digital organism (DO), a subsystem characterized by a set of peculiar features and resources it can offer to the rest of the ecosystem for use from its peer DOs. The internal organization of the DO must address issues of management of its own resources, including power consumption. Inside the DO and among DOs, peer-to-peer interaction mechanisms can be conveniently deployed to favor resource sharing and data dissemination. Throughout this paper, we show that most of the solutions and technologies needed to construct a digital ecosystem are already available. What is still missing is a framework (i.e., mechanisms, protocols, services) that can support effectively the integration and cooperation of these technologies. In addition, in the following we show that that framework can be implemented as a middleware subsystem that enables novel and ubiquitous forms of computation and communication. Finally, in order to illustrate the effectiveness of our approach, we introduce some experimental results we have obtained from preliminary implementations of (parts of) that subsystem.Comment: Proceedings of the 7th International wireless Communications and Mobile Computing conference (IWCMC-2011), Emergency Management: Communication and Computing Platforms Worksho

    Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

    Get PDF
    In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

    Wireless Play and Unexpected Innovation

    Get PDF
    Part of the Volume on Digital Young, Innovation, and the Unexpected. This chapter considers play as leading to unexpected innovation in advanced wireless technologies. It concludes that much of the potential for new media to enhance innovation actually echoes much older patterns, as evidenced by comparisons to wireless history. These are patterns of privilege, particularly class and gender privilege, reinforced by strict intellectual property protections. Detailed case studies are presented of the "wardrivers," young male computer enthusiasts who helped map wi-fi signals over the past decade, and of earlier analog wireless enthusiasts. The chapter offers a solid critique of many present-day celebrations of technology-driven innovation and of the rhetoric of participatory culture

    Embedded Trusted Monitoring and Management Modules for Smart Solar Panels

    Get PDF
    This paper investigates developing a prototype of smart solar panels. This architecture consists of a panel monitoring module and the central management unit. The monitoring module is to be embedded inside each PV panel making it secure to transfer the trusted data via Wi-Fi to the central Management unit (which can accommodate an array of PV panels in an installation). This module is required for data storage and provides the ability to upload secure data to the cloud. This platform presents the ability to securely manage large numbers of rooftop solar panels in a distributed ledger by implementing block chain algorithm. For achieving this purpose, Module 400 is envisaged to be turned into a Blockchain node as it provides the infrastructure to implement this technology

    Overcoming Poverty through Digital Inclusion

    Get PDF
    A growing body of research is showing how digital inclusion can help communities overcome poverty and injustice. The main challenge lies in how best to achieve this goal. The authors argue that digital inclusion must occur in two distinct stages. The first stage is digital literacy, accomplished with the Symbiotic Computer (SC)-smartphones and tablets. The second stage will be professional capacity-building, accomplished with the more traditional Personal Computer (PC)
