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.

当今的许多网络包括在无线连接的情况下操作的移动的设备、用户及其应用，其中关于本质上动态的操作上下文的表达性和广泛的知识可以显著地增强和实现新形式的行为。 随着我们本地感知、计算和通信能力的提高，我们必须在这些日益连接的环境中重新审视传统的上下文和上下文感知概念，这些环境由分布式实体之间的协调和合作定义。 在这种情况下，这个项目解决了以下基本的研究问题：我们如何表达的基础上确定的实体群体的谓词在个人实体和群体的上下文，以及我们如何定义，评估和共享个人和群体的上下文？该项目从背景和背景意识的角度出发，偏离了现有的工作。 现有的工作主要是以自我为中心的，重点是如何使用单个实体的情况的知识来影响自己的个人，本地行为。 随着群体成为物联网、延迟容忍网络和智能交通系统等不同领域应用的决定性力量，共享上下文视图的概念将变得至关重要。 第二个关键的区别是该项目对关于上下文和组成员的分布式知识的质量的关注。 使这些质量指标可用于应用程序，对于实现基于上下文信息的有效决策至关重要。该项目解决了我们日常生活中普遍存在的上下文感知问题。 此外，该项目还包括一个综合影响计划，利用技术转让吸引公众参与并评估研究。 为了扩大参与，该项目包括为本科生，K-12参与者，研究生和研究人员参加重点相关活动的设计机会。
