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

该项目正在对通过激励机制促进的协作广域无线服务的设计进行初步调查。与广域无线环境中现有的服务模型不同，在广域无线环境中，服务交互是在相对较长的时间尺度上与单个提供商进行协商的，本研究考察了一种灵活的服务模型，其中服务交互是在任意时间尺度上与多个提供商按需协商的。正在进行的工作是迈向这种新服务模型的第一步，该模型将基础设施提供者与服务提供者分离，支持细粒度竞争，并促进基于用户和应用程序需求的灵活组合。在第一步中所追求的研究问题有两个方面：(i)会计、服务验证和信任管理，以有效地实现协作服务；（ii）设计和实现允许移动设备和第三方服务之间灵活交互的中间件。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。该项目的预期结果将是对新服务模型的可行性进行基于原型的演示。这项工作将通过会议和期刊上的出版物、软件和随附文件的公开分发加以传播，并有可能作为将来实际部署的种子。

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.
