Figure 2 – Operation mode change for IoT applications temporally providing resources to
external safety systems during disaster

IoT applications designed for users within a building or other environment equipped with a safety
system should temporally (during disaster) share both the IoT application control capability and all
kinds of measurement data with the safety system. These resources might be useful for the safety
system operation, for example, data from the various sensors such as temperature and humidity in
case of fire.

To simplify the integration of IoT applications with external safety systems, it is recommended to
use CAP [ITU-T X.1303] for the interaction between IoT applications and external safety systems.
CAP is a two-way communication protocol that can enable both the transmission of data from IoT
applications to safety systems and the transmission of alert messages from safety systems to IoT
applications.
The main disadvantage of this operation strategy is the possibility of failures of functional
components of the IoT infrastructure if these are not designed to operate correctly during disaster.
Such failures, in the case of functional components that are needed during disaster management
processes, may cause negative consequences. These failures are possible due to the fact that there
are no special certification procedures for the functional components of the IoT infrastructure to
ensure correct operation during disaster, in contrast to the certified procedures of safety systems.

7.3 IoT applications with external control of operation during disaster
The third operation strategy for IoT applications during disaster involves a complete transfer of
control capabilities and measurement data from IoT applications to external safety systems or
external control centres.
NOTE 1 – The complete transfer of control capabilities implies the termination of the resource management
process by the IoT application itself.
NOTE 2 –An external control centre may be, for example, an organization or a functional unit of an
organization that carries the full legal and administrative responsibility for correct disaster management in a
given area.
Figure 3 shows the operation mode change of IoT applications following this operation strategy.
