While previous Intranet of Things, which is a local network of wireless sensor networks, machine-to-machine can only extract regional information containing specific content from the things, The IoT works on two paradigms: 1) interaction between humans and 2) interaction between things. But mostly humans don't use much data from things like client-server model. Social networks are the topic for discussion as the demand for social networking is growing and IoT now can be referred as Social IoT.
