NetSE: Large: Collaborative Research: Platys: From Position to Place in Next Generation Networks

该项目开发了环境的高级概念，该概念利用下一代网络的功能来支持提供更好用户体验的应用程序。特别是，它利用移动设备--总是与用户一起--来捕获上下文的关键元素：用户的位置，以及通过本地化，用户环境的特征。对用户体验来说，重要的是用户的位置：概念上的位置，如“在家里”、“慢跑”或“杂货店购物”--将位置与活动、环境属性和附近其他人的活动结合在一起的描述。要实现这种位置概念，需要来自设备和基础设施的信息以当前网络架构中未曾预料到的方式流动。它假定在保护用户隐私的同时启用机会主义交互，并设计激励机制来促进合作而不利用任何。上述架构关注的问题远远超出了传统的网络主题，例如路由。该项目将开发、演示和评估一种将用户体验放在首位的新型网络架构。它将在语义语境建模、多层次抽象的移动性跟踪、协作本地化和激励机制方面带来理论上的进步。提供增强用户体验的联网应用程序将为行业以及公民的生产力和生活质量带来巨大回报。一个原型系统将在大学环境中实施和评估情景感知服务，并有望扩展到K-12学校和公共设施。

This project develops a high-level notion of context that exploits the capabilities of next generation networks to enable applications that deliver better user experiences. In particular, it exploits mobile devices -- always with a user -- to capture key elements of context: the user's location and, through localization, characteristics of the user's environment. What matters for the user experience is the user's place: a location in conceptual terms such as "at home," "jogging," or "grocery shopping" -- descriptions that combine positions with activities, environmental properties, and the activities of other nearby people. Realizing this notion of place requires that information from devices and infrastructure flow in ways unanticipated in current network architectures. It presumes enabling opportunistic interactions while preserving the users' privacy and designing incentive mechanisms to promote cooperation without exploitation of any. The above architectural concerns lie far beyond traditional network topics such as routing.This project will develop, demonstrate, and evaluate a novel network architecture that gives primacy to user experience. It will lead to theoretical advances in semantic context modeling, mobility tracking at multiple levels of abstraction, collaborative localization, and incentive mechanisms. Networked applications offering enhanced user experience will have significant payoffs for industry and the productivity and quality of life of citizens. A prototype system will implement and evaluate context-aware services in university settings with prospects of expansion to K-12 schools and public facilities.
