  • Blockchain-Enabled Security in Electric Vehicles Cloud and Edge Computing
    IEEE Network, 2018
    Co-Authors: Hong Liu, Yan Zhang
    Abstract:

    EVCE computing is an attractive Network Paradigm involving seamless connections among heterogeneous vehicular contexts. It will be a trend along with EVs becoming popular in V2X. The EVs act as potential resource infrastructures referring to both information and energy interactions, and there are serious security challenges for such hybrid cloud and edge computing. Context-aware vehicular applications are identified according to the perspectives of information and energy interactions. Blockchain-inspired data coins and energy coins are proposed based on distributed consensus, in which data contribution frequency and energy contribution amount are applied to achieve the proof of work. Security solutions are presented for securing vehicular interactions in EVCE computing.

  • mobile edge computing for vehicular Networks a promising Network Paradigm with predictive off loading
    IEEE Vehicular Technology Magazine, 2017
    Co-Authors: Ke Zhang, Yejun He, Supeng Leng, Yuming Mao, Yan Zhang
    Abstract:

    Cloud-based vehicular Networks are a promising Paradigm to improve vehicular services through distributing computation tasks between remote clouds and local vehicular terminals. To further reduce the latency and the transmission cost of the computation off-loading, we propose a cloud-based mobileedge computing (MEC) off-loading framework in vehicular Networks. In this framework, we study the effectiveness of the computation transfer strategies with vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication modes. Considering the time consumption of the computation task execution and the mobility of the vehicles, we present an efficient predictive combination-mode relegation scheme, where the tasks are adaptively off-loaded to the MEC servers through direct uploading or predictive relay transmissions. Illustrative results indicate that our proposed scheme greatly reduces the cost of computation and improves task transmission efficiency.

  • the Network Paradigm in organizational research a review and typology
    Journal of Management, 2003
    Co-Authors: Stephen P Borgatti, Pacey Foster
    Abstract:

    In this paper, we review and analyze the emerging Network Paradigm in organizational research. We begin with a conventional review of recent research organized around recognized research streams. Next, we analyze this research, developing a set of dimensions along which Network studies vary, including direction of causality, levels of analysis, explanatory goals, and explanatory mechanisms. We use the latter two dimensions to construct a 2-by-2 table cross-classifying studies of Network consequences into four canonical types: structural social capital, social access to resources, contagion, and environmental shaping. We note the rise in popularity of studies with a greater sense of agency than was traditional in Network research.

  • ethical and strategic issues in organizational social Network analysis
    The Journal of Applied Behavioral Science, 2003
    Co-Authors: Stephen P Borgatti, Jose Luis Molina
    Abstract:

    Social Network analysis is increasing rapidly in popularity, both in academic research and in managementconsulting. The conceptof Network has become the metaphor for understanding organizations. Academics see the Network Paradigm as a way to escape from the atomism of traditional social science in which individual behavior—such as adoption of an innovation—is analyzed solely in terms of the attributes of the individ ual (e.g., openness to change, stake in the outcome, etc.) and not in terms of interper sonal transmission, influence processes, and other relational variables. Management practitioners are interested in Network methodology because it provides a way to make

  • The City Network Paradigm: Theory and Empirical Evidence
    Urban Dynamics and Growth: Advances in Urban Economics, 2005
    Co-Authors: Roberto Camagni, Roberta Capello
    Abstract:

    Abstract Real city systems in advanced countries have significantly departed from the abstract Christallerian pattern of a nested hierarchy of centers and markets. The reduction in transport costs and the demand for ‘variety’ by the consumer have broken the theoretical hypothesis of separated, gravity-type, non-overlapping market areas. ‘Location economies’ as described by Hoover, and synergy elements operating through horizontal and vertical linkages among firms, have led to the emergence of specialized centers, in contrast to the typical despecialisation pattern deriving from the theoretical model. High-order functions sometimes locate in small (but specialized) centers where the model expectations are only for lower-order functions. In recent years, Network behaviour has extensively been analysed as the emerging model for economic growth. By Network behaviour, a metaphor for cooperative behaviour among individuals, corporate or territorial partners is intended - which is increasingly becoming the reference Paradigm in an era of continuing innovation and fast technological change, in the presence of “market failure” when dynamic and innovative behaviours are concerned and of the high costs of a growth strategy based on the sole internal know-how. The chapter provides insights into the economic rational of this behaviour, by approaching the issue treating cities and territories both as individuals and as collective actors. Moreover, the chapter provides empirical evidence on the existence of “city Networks” and on the advantages cities gain from being part of a Network.

  • Industrial Enterprises and Economic Space: the Network Paradigm
    European Planning Studies, 1996
    Co-Authors: Roberta Capello
    Abstract:

    Abstract This paper is an extended review essay stimulated by the book of Conti, Malecki and Oinas (1995) on The Industrial Enterprise and its Environment. Three different Paradigms of industrial organization are outlined with what has earlier been referred to as the Network Paradigm best capturing contemporary realities. The spatial implications of this framework are then drawn out and the limits of the Paradigm summarized.

  • new organizational forms for competing in highly dynamic environments the Network Paradigm
    British Journal of Management, 1996
    Co-Authors: David W. Cravens, Nigel F. Piercy, Shannon H Shipp
    Abstract:

    Turbulence and rapid change in the business environment have been associated for some time with the development of new Network organizational forms which put various types of strategic alliance and other inter-organizational collaborations into effect. This paper traces the rationale for the formation of such Networks and the associated vertical disaggregation of functions and implications for internal organizational design. This leads to the proposal of a classification framework for Network forms. Using the dimensions of volatility of environmental change on the one hand, and the type of inter-organizational relationship involved (collaborative or transactional) on the other hand, Network forms are classified as: hollow Networks, flexible Networks, value-added Networks and virtual Networks. In each case it is possible to identify the environmental and organizational contingencies most likely to be associated with the emergence and adoption of a particular type of Network arrangement. This argument leads to the identification of a new research agenda which has the goals of developing more robust conceptualizations of Network characteristics; better understanding the contingencies surrounding the emergence of Network forms and their relative efficiencies and specifying some of the major implications of Network formation for internal organizational design. In parallel the paper identifies a number of managerial implications for setting strategic priorities and developing appropriate management systems in these new organizational contexts.
