IoT has emerged as an unprecedented paradigm with great potential for changing how people interact, think and live. It is making existing Internet services feasible in ways that were previously impossible, as well as paving the way for new situation- awareness applications suitable for smart cities, such as realtime video surveillance, traffic control, and emergency management. These applications will typically rely on large numbers of IoT devices to collect and collaboratively process streamed data to enable real-time decision making. In this article, we introduce the concept of Semantic Virtual Space (SVS), an abstraction for virtualized cloud-enabled IoT infrastructure that is commensurate with the goals and needs of these emerging smart city applications, and propose and discuss scalable architectures and mechanisms that enable and automate the deployment and management of multiple SVS instances on top of the cloud-enabled IoT infrastructure.

利用区块链释放参与式物联网的力量，提高智慧城市的安全性和态势感知能力


物联网已经成为一种前所未有的范例，具有改变人们互动、思考和生活方式的巨大潜力。它使现有的互联网服务以以前不可能的方式变得可行，并为适合智慧城市的新的态势感知应用铺平了道路，例如实时视频监控、交通控制和应急管理。这些应用程序通常依赖大量物联网设备来收集和协作处理流数据，以实现实时决策。在本文中，我们介绍了语义虚拟空间（SVS）的概念，这是一种虚拟化云支持的物联网基础设施的抽象，与这些新兴智慧城市应用的目标和需求相称，并提出和讨论了可扩展的架构和机制，以实现并在支持云的 IoT 基础设施之上自动部署和管理多个 SVS 实例。
