CNS Core: Small: Scaling the IoT with Constellation

该项目旨在实现物联网（IoT）无处不在、人人可及的愿景。如今，物联网被孤立在一些小众应用程序中，这些应用程序包含不能跨供应商互操作的智能设备。星座项目的目标是创建允许嵌入式物联网设备易于发现、共享、管理、连接和保护所需的软件，以使物联网能够扩展。Constellation包含一种新的编程语言，它允许程序员轻松地指定语义意图，从而使系统能够定位最佳设备、处理故障、解决冲突并满足性能目标。Constellation依赖于位于物联网设备附近的边缘计算节点的存在，这些节点形成了实现这一愿景所需的计算和通信服务网络。物联网革命尚处于起步阶段，但对社会的影响已经显而易见。自动驾驶汽车带来便利，智能电表带来节能，智能家居带来安全。然而，物联网是碎片化的、孤立的和孤立的。为了实现智慧校园、智慧城市等的愿景，需要物联网在这些孤岛之间相互连接，以实现提高安全性、节能性、生产力和健康的新应用。这是星座计划的最终目标。该提案中所设想的物联网的发展还需要与行业合作，从而刺激创造新的创新领域，从而创造就业机会。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to realize a vision of the Internet-of-Things (IoT) that is ubiquitous and accessible to all. Today, the IoT is siloed with a few niche applications containing smart devices that do not interoperate across vendors. The goal of this project, Constellation, is to create the software needed to allow embedded IoT devices to be easily discovered, shared, managed, connected, and protected to enable the IoT to scale. Constellation contains a new programming language that allows programmers to easily specify semantic intent allowing the system to locate the best devices, handle failures, resolve conflicts, and meet performance goals. Constellation relies on the presence of edge computing nodes located near the IoT devices that form a web of computation and communication services needed to realize this vision. The IoT revolution is at its infancy yet the impact on society is already evident. Self-driving cars promise convenience, smart meters promise energy savings, and smart homes promise safety. Yet the IoT is fragmented, siloed, and isolated. To realize the vision of a smart campus, smart city, and beyond, requires that the IoT be interconnected across these silos to enable new applications that promote greater safety, energy savings, productivity, and wellness. That is the ultimate goal of Constellation. The growth of the IoT envisioned in this proposal will also require partnership with industry thus stimulating the creation of new frontiers of innovation that lead to job creation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
