  Along with the rapid development of Internet and cyber techniques, the
Internet of People (IoP) has been emerging as a novel paradigm which
establishes ubiquitous connections between social space and cyberspace. Unlike
the Internet of Things (IoT), human nodes in IoP are not only terminal users,
but also significant participants bonded with tighter relationships. Note that
IoP has deeply influenced our lives. For example, the prosperity of social
media enables us to build and maintain new relationships without considering
physical boundaries. In this paper, we give a comprehensive overview of IoP by
comparing it with IoT, introduce its enabling techniques from aspects of
sensing, communication and application. In addition, we summarize and compare
popular IoP-enabled platforms according to different functions, and finally
envision open issues needed to be further discussed in IoP. It provides
constructive suggestions, lays solid foundations, and makes a basic blueprint
for the future development of IoP paradigm.
