RESEARCH, ANALYSIS & TRENDS

Communication models in IoT

The fact is that IoT devices will be found everywhere
and will enable ambient intelligence in the future.
Therefore, the overview of the various communication
models used in IOT, given below, are of great value.
The IoTs allow people and things to be connected
anytime, anyplace, with anything and anyone, ideally
using any path/network and any service. From an
operational perspective, it is useful to think about how
IoT devices connect and communicate in terms of their
technical communication models, before making
decisions:

• The device-to-device communication
model represents two or more devices that
directly connect and communicate between one
