Energy and Security
standard is essential to proliferate consumer IoT
devices and PIoT networks. The future study of
3GPP must focus on PIoT to support the service
and functional requirements, identify the characteristics
of PIoT networks, and simplify the network
architecture to enable the 3GPP network to
support PIoT functionalities seamlessly. Besides,
the 5Gs also must study the gap analysis between
the identified requirements and what is already
defined by existing 3GPP requirements.
CYBERSECURITY ASPECTS OF PIoT
Possible security threats in PIoT are comparatively
lower than the IoT due to its limited exposure
to public networks. Unlike IoT, we can
categorize the PIoT threats in the two parts, i.e.,
device level, communication level.
Device capture, device tampering, and device
outage are prevalent attacks in device-level
threats. On the one hand, PIoT has limited chances
to be exposed to device-level attacks; however,
it cannot be ignored altogether; on the
other hand, PIoT is prone to communicationlevel
attacks. Generally, PIoT devices communicate
to the Cloud data center through cellular
network gateways. Usually, these gateways are
open to public networks and may lead to network
attacks, such as selective forwarding,
blackhole, wormhole attack.5 Existing security
solutions may be taken as a base to secure the
PIoT5; however, it demands new security solutions
with application specifications.
ENERGY ASPECTS OF PIoT
Energy-aware is a crucial design goal in a wide
range of IoT devices, such as wearables and sensors.1
However, the current IoT standards do not
support very short-range low energy-consumption
capabilities. Thus, enhancements in energy consumption
optimization for PIoT devices become
essential. One way to go with this is to optimize
thedatatrafficthat can providesignificantenergy
saving, e.g., small data transmission. Besides, a
gap analysis requires between the identified
requirements for PIoT and what is already defined
for IoT requirements.
CONCLUSIONS
The PIoT comprises a set of IoT devices that
communicate between themselves andwith a local
gateway. Although communication among IoT
devices is not entirely new, but creating a PIoT networks
requires lots of nonautomated configurations,
towhich a usermight find difficult.
