Many of today's networks include mobile devices, users, and their applications operating in wirelessly connected situations, where expressive and extensive knowledge about the intrinsically dynamic operating context can significantly enhance and enable new forms of behavior. As our capabilities to locally sense, compute, and communicate increase, we must reexamine traditional notions of context and context-awareness in these increasingly connected environments, which are defined by coordination and cooperation among distributed entities. In this light, this project addresses the following fundamental research questions: how do we expressively identify groups of entities based on predicates over individual entities' and groups' contexts, and how do we define, assess, and share the context of both individuals and groups? This project diverges from existing work in its perspective on context and context-awareness. Existing work is largely ego-centric, focusing on how to use knowledge of a single entity's situation to impact its own personal, local behavior. As groups become a defining force of applications in domains as diverse as the Internet of Things, delay-tolerant networks, and intelligent transportation systems, the notion of a shared view of the context will be of primary importance. A second key differentiator is the project's focus on the quality of distributed knowledge about both context and group membership. Making these quality metrics available to applications is essential to enabling effective decision-making based on context information. The project addresses issues surrounding context-awareness that pervade our everyday lives. In addition, the project includes an integrated impact plan that uses technology transfer to engage the public and evaluate the research. To broaden participation, the project includes design opportunities for undergraduate students, K-12 participants, and graduate students and researchers to participate in focused related activities.

当今的许多网络都包括移动设备，用户及其在无线连接的情况下运行的应用程序，在这种情况下，有关本质动态操作环境的表达和广泛的知识可以显着增强和启用新的行为形式。 作为我们在本地意义，计算和交流增加的能力，我们必须在这些日益连接的环境中重新审查传统的上下文和上下文意识的概念，这些概念是由分布式实体之间的协调和合作定义的。 从这个角度来看，该项目解决了以下基本研究问题：我们如何根据个人实体和群体的环境表达识别实体群体，以及我们如何定义，评估和分享个人和群体的背景？该项目在上下文和上下文意识上与现有工作不同。 现有的工作主要以自我为中心，重点是如何利用单个实体状况的知识来影响其个人的本地行为。 随着小组成为物联网，延迟耐受性网络和智能运输系统等多样性的应用程序的决定性力量，对上下文的共同观点的概念将至关重要。 第二个关键区别是该项目对分布式知识的质量既有上下文和小组成员资格。 将这些质量指标用于应用程序对于基于上下文信息实现有效的决策至关重要。该项目解决了围绕我们日常生活的上下文意识的问题。 此外，该项目还包括一项综合影响计划，该计划使用技术转移来吸引公众并评估研究。 为了扩大参与，该项目包括本科生，K-12参与者以及研究生和研究人员参加专注相关活动的设计机会。
