Wi-Fi and 5G 187
The issue stems from the new generation of Home Gateway, which
raises the question of management of IP in the terminal machine. For
television sets, telephones and other fairly important machines, the
presence of an IP component poses no problem: this is what we find in
IPTV or IP telephony. On the other hand, for a very cheap sensor or
device, it is either impossible or too costly to introduce an
IP component and have an intermediary machine such as a controller.
The controller can also be integrated into the Home Gateway. HIP,
described a little earlier, can be used to perform communications,
firstly with the sensor, and secondly with the Home Gateway.
In conclusion, the home contains a large number of “things” which
it is possible to connect. Therefore, the Home Gateway is of prime
importance, as it allows us – perhaps with a controller – to manage not
only the communications, but also the security and quality of service
of the “things” in the home.
6.28. Conclusion
5G is an environment that brings together numerous networks with
different architectures and different protocols. This combination of
technologies to form 5G is made possible by the arrival of the Cloud,
Cloudlets, SDN (Software-Defined Networking) and SDR (SoftwareDefined Radio). Its design ranges from D2D-type solutions to the
connection of billions of more or less intelligent things. Virtualization
plays an important role because, almost everywhere, there is a
decoupling between the physical device and the control device, which
is usually situated in a datacenter specialized for the application.
The Internet of Things is becoming a reality thanks to RFID and
sensors. However, we are still a long way from being able to
completely integrate all these small devices, because they are not
powerful enough to support TCP/IP, and yet they are rather energyhungry. In order to achieve this goal, we need to use very specific
gateways, which can include the connected things on the one hand,
and the Internet on the other. HIP could become the fundamental
standard of this connection solution.
