NeTS-NBD: An Open Market Architecture for Wide-area Wireless Services

该项目正在进行一项初步调查，以设计通过激励措施促进的协作广域无线服务。不同于现有的服务模式，在广域无线环境中，服务的互动是一个相对较长的时间尺度与一个单一的供应商进行谈判，本研究探讨了一个灵活的服务模式，服务的互动进行谈判的需求与多个供应商在任意的时间尺度。正在进行的工作是迈向这种新的服务模式的第一步，这种模式将基础设施提供商与服务提供商相结合，实现细粒度的竞争，并促进基于用户和应用需求的灵活组合。在这第一个步骤中追求的研究问题是双重的：（一）会计，服务验证和信任管理，以有效地实现协作服务，以及（二）设计和实现的中间件，允许灵活的移动的设备和第三方服务之间的交互。该项目的重点是实验性的，目的是证明所提出的方法在现实情况下的可行性。该项目的预期成果将是以原型为基础展示新服务模式的可行性。这项工作将通过在会议和期刊上发表、公开分发软件和附带文件的方式传播，并有可能被用作未来实际部署的种子。

This project is conducting a preliminary investigation in the design of collaborative wide-area wireless services facilitated through incentives. Unlike the existing service model in wide-area wireless environments where service interactions are negotiated with a single provider for a relatively long timescale, this research examines a flexible service model where service interactions are negotiated on-demand with multiple providers at arbitrary timescales. The ongoing work is the first step towards this new service model which decouples infrastructure providers from service providers, enables fine-grained competition, and promotes flexible composition of such services based on user and application needs. The research questions being pursued in this first steps are two-fold: (i) accounting, service validation and trust management to efficiently implement collaborative services, and (ii) design and implementation of a middleware that allows flexible interactions between the mobile devices and third-party services. The focus of the project is experimental with an objective to demonstrate the feasibility of the proposed approach in realistic scenarios. The expected results of this project will be a prototype-based demonstration of the feasibility of the new service model. The work will be disseminated through publications in conferences and journals, public distribution of software and accompanying documentation, and can potentially be used as a seed for realistic deployments of in the future.
