4) satisfying embedded control
constraints for performance
optimization
5) utilizing intelligent and predictive decision making based on
iot functionalities.
the real-time collection and handling of data for countless numbers
of embedded sensors and the optimal control of actuator signals require
an advanced Bems controller platform that would be capable of resolving big data issues.

The IoT

The IoT is an
enabling technology
for sensing,
transmitting, and
receiving command
signals through
communication
channels, including
the Internet
or Ethernet.

the iot is an enabling technology
for sensing, transmitting, and receiving command signals through communication channels, including the
internet or ethernet. the iot interconnects distributed
things (components and devices) and allows them to work
together to perform certain tasks, as shown in figure 1.
the outlook for the iot is to increase the number of internet-connected devices that can enhance many aspects of
human life. it would revolutionize internet functionalities,
transform raw data into usable information (and, consequently, knowledge), and create better living conditions
with respect to the large quantity of embedded knowledge
that is made available to humans for decision making. the
key components of the iot are sensors, communication
networks, smart software algorithms, data aggregators,
service providers, and security protocols. the iot has been
implemented in several countries, including Denmark,
south Korea, and switzerland, which already has the largest amount of internet-connected appliances in the world.
however, it is envisioned that the availability of the internet is no longer a stumbling block for offering a remarkable iot test bed in nearly all countries worldwide.
one of the viable solutions that resolve the Bems data
collection and management challenge in large buildings
is to integrate a Bems with iot technology. iot utilization
would lead to the interconnection of sensors, actuators,
and controllers in all of the Bems layers and provide the
Bems controller with an opportunity to monitor and
manage all of the building components within a large
network. in contrast to traditional Bems applications,
wherein building units are operated and controlled independently and a central controller manipulates the system devices, iot integration allows all of the building
units and devices that are capable of exchanging data
and interacting with each other to be interconnected and
controlled in a distributed manner. the iot facilitates the
use of archived data along with those of large-scale, realtime sensors in a Bems to enhance the overall efficiency
of the iot-enabled Bems for a transition toward smart
building management.

sensors play a critical role in iot
applications; they aggregate an extended set of data ranging from the temperature to indoor and outdoor air quality
and other indicators for Bems controllers, which manage the performance
and safety of all of the building devices.
Providing this type of building control
requires cogent sensors at the edge of
the communication network in addition to data-processing units in central
layers of Bems operations. the iot
offered by the intel corporation consists of five principal services: edge-tocloud, mobility, data processing,
security, and collective relevance,
which changes the Bems into a smart
system. the iot possesses a cloud server to store the collected data, and the
large sum of stored data on the cloud server can tremendously enhance Bems functionality since the realtime Bems controller awareness would be extended to
both inside and outside building conditions. for instance,
the proposed iot applications will benefit from the large
hvac data collected for the Bems controller, which were
not utilized in traditional Bems applications.
smart buildings offer much potential for assembling
various types of data as input signals that can be used to
execute the Bems optimization for accommodating building operation constraints. generally, sensor data are sent
to a Bems after being filtered, processed, and secured by
gateways and big data mining software embedded in the
iot layer. then, the Bems software processes the received
data using embedded control and optimization functions
and sends proper signals to actuators. the transition of a
conventional Bems to an intelligent iot-enabled energy
management system awards the Bems for stretching its
