Unleashing the potential of the Internet of Things 3

8.13 Mobility support

IoT devices can be either mobile or static. When an IoT device moves from place to place, it is
necessary to support mobility at the application level (such as service mobility between different
service providers) as well as the network level. Therefore, IoT applications are recommended to
support mobility of IoT devices.

8.14 Scalability support
As stated in clause 7.5, the scale of the network of IoT devices may be huge. IoT applications are
recommended to support scalability, including the number of devices, the volume of data traffic that
needs to be communicated, etc.

8.15 Robustness against dynamic changes

Clause 7.4 describes dynamic change of status of an IoT device. Therefore, IoT applications are
recommended to provide robustness, e.g., seamless continuity and sustainability, against dynamic
transformation and change of IoT devices.

8.16 Self-organization (re-organization) and self-healing

IoT devices may provide maintenance-free operation and may be self-adaptable as described in
clauses 7.8 and 7.9. For coping with these characteristics, IoT applications are recommended to
support self-organization (re-organization) and self-healing of the application and the network on the
IoT device to recover from failure or mal-function. This requirement is related to robustness against
dynamic transformation and changes in clause 8.15.

8.17 Energy efficient operation
IoT applications are recommended to operate IoT thing devices in a way that minimizes the necessary
energy for operation. This will ensure longer battery life, if the devices are battery-operated (see
clause 7.10), and longer maintenance-free operation (see clause 7.8). This will also help reduction of
carbon gas emissions.

8.18 Common data format for collaborative data processing
IoT applications are recommended to adopt common data formats (see clause 7.7). This is to facilitate
the mixing and mashing of data gathered by many IoT applications (which adds value to the collected
data as a whole) as well as to facilitate data exchange.
