accomplished independently. To prevent the leak and certify the published privacy data,
anonymization infrastructure is indispensable for the future SSC applications including big‐data
business.

2.2.4 Augmented reality
The potential of the use of augmented reality is infinite and they are still discovering many of their
applications, for example, new augmented reality technology takes designs of proposed building
developments and transposed them onto a smartphone or similar device. Using this, the inhabitants
of a smart sustainable city can visualize how the final result would be to make informed planning
decisions. Police services can use viewers of augmented reality with facial recognition for
identification of criminals, and tourists can be guided and can also display information of the
attractions or monuments of the city, etc.

2.3 Terminals, Sensing and multi‐device layer

This section contains specifications for the users layer (Figure 5) and sensing layers (Figures 4 and 5).

2.3.1 Terminals (Gateways)
The network is not complete without interconnection equipment on the one hand and on the other
with their ends that reach users and things. Sensors are one of the most important types of terminals,
which are discussed in the next section.

2.3.2 Sensor
They consist of sensors of resources, security, lighting, presence, weather, transportation,
movement or position installed on the physical infrastructure of the SSC. These devices make it
possible to meet and study the phenomena of public and private interest such as climate, congestion
