3 Unleashing the potential of the Internet of Things

• determining the disaster area and the nature and parameters of the disaster, taking into
account the information obtained from the IoT devices under its jurisdiction and external
sources of information (e.g., emergency agencies);

• managing the IoT devices under its jurisdiction in order to safely evacuate people from the
disaster area;

• recording and storing information obtained during disaster and the history of operations
during disaster.

I.2 The distribution of the monitoring and control centre's responsibilities to local centres
Ubiquitous IoT devices are present in large quantities in apartments, houses, organizations, streets,
public places, etc.
In the case of a monitoring and control centre for IoT devices, it is possible for all IoT devices in a
given house or building to be under the jurisdiction of one local centre. Similarly, all IoT devices in
other areas, for example, on the same street, could be managed by other local centres. All these
local centres could be integrated into the infrastructure of the root Centre.
The infrastructure of the root Centre can be organized as a multi-level hierarchy containing
monitoring and control nodes of several levels responsible for IoT devices in different: buildings
(local centres), cities (municipal centres), regional (regional centres) and countries (federal centres).
Additionally, the responsibility of local centres may be distributed on an IoT device purpose basis.
For example, the Centre may manage several local centres, one being responsible for IoT devices
for household purposes, another for IoT devices for traffic management purposes, a third one for
IoT devices for security system purposes, etc.

The following clauses describe possible working scenarios of the monitoring and control centre.

I.3 The monitoring and control centre's working scenarios
The main goal of the Centre is to check the integrity and reliability of the information provided by
the IoT devices under its jurisdiction. This goal can be achieved in the following ways:
1. comparing the sensors' readings of the IoT devices under the Centre's jurisdiction, with the
readings of autonomous (duplicated) sensor networks;
2. intelligent monitoring of the sensors' readings, under the Centre's jurisdiction, consisting of
data collection and mathematical analysis (data mining) of the obtained information, thus
allowing the identification of IoT device malfunctions.
Both methods may be implemented and used in combination in the appropriate proportion.

The above methods are described in more detail in clauses I.3.1 and I.3.2.
I.3.1 Autonomous sensor network

The Centre deploys autonomous sensor networks containing sensors of various physical parameters,
which duplicate the sensors of the IoT devices under the Centre's jurisdiction.

The autonomous sensor network is required to cover the entire area under the Centre's jurisdiction.
For instance, a local indoor centre should deploy a sensor network which covers the indoor area that
contains IoT devices under the Centre's control.

The sensors of this autonomous sensor network are considered reference sensors, i.e., their readings
are taken as reference values of physical parameters in this area. It is expected that the reference
sensors are certified by a trusted and properly certified organization.

The Centre collects data from the IoT devices under its jurisdiction, and compares them with the
reference values. On this comparison basis, the Centre makes decisions about integrity and
reliability of the data produced by the IoT devices.
