As a paradigm of Internet of Things (IoT), social sensor cloud (SSC), which connects the social networks and the sensor networks as well as the cloud, is receiving growing attention from both the academic and industrial communities. Aiming to be a timely guidance with respect to SSC, this article investigates SSC from four perspectives: framework, greenness, issues, and outlook. Specifically, a framework for SSC is introduced first. Then, with the initiative to reduce the carbon footprint, the mechanisms that enable green SSC are discussed. With that, the open research issues for SSC are presented. Finally, an outlook for SSC is shown.

社交传感器云：框架，绿色，问题和展望

作为物联网（IoT）的范例，连接社交网络和传感器网络以及云的社交传感器云（SSC）受到了学术界和工业界的越来越多的关注。为了对SSC提供及时的指导，本文从以下四个方面对SSC进行了研究：框架，绿色，问题和前景。具体来说，首先介绍SSC的框架。然后，在减少碳足迹的倡议下，讨论了实现绿色SSC的机制。这样，就提出了SSC的开放研究问题。最后，显示了SSC的前景。
