Internet Of Things - The new era (part 1 of 2)
Our topic today is the current trend in the
world of technology, it’s a huge topic but I divided it to two parts, the first
one is the definition of IoT and the second is the cyber security part, so let’s
get it started.
The Internet of things (IoT) is the inter-networking of physical devices, vehicles
(also referred to as "connected devices" and "smart devices"),
buildings, and other items embedded with electronics, software, sensors, actuators,
and network connectivity which enable these objects to collect and
exchange data. The IoT allows objects to be sensed or controlled remotely
across existing network infrastructure, creating opportunities for more
direct integration of the physical world into computer-based systems, and
resulting in improved efficiency, accuracy and economic benefit in addition to
reduced human intervention. When IoT is augmented with sensors and actuators,
the technology becomes an instance of the more general class of cyber-physical
systems, which also encompasses technologies such as smart grids, virtual
power plants, smart homes, intelligent transportation and smart
cities. Each thing is uniquely identifiable through its embedded computing
system but is able to interoperate within the existing Internet infrastructure.
Where the term IoT came from? In 2016, the vision of the Internet of things has evolved due to a
convergence of multiple technologies, including ubiquitous wireless
communication, real-time analytics, machine learning, commodity sensors, and embedded systems. This
means that the traditional fields of embedded systems, wireless sensor networks, control
systems, automation (including home and building
automation), and others all contribute to enabling
the Internet of things (IoT).

Where the IoT can be implemented?
Media: The aim
is of course to serve, or convey, a message or content that is (statistically
speaking) in line with the consumer's mindset. For example, publishing
environments are increasingly tailoring the messages (advertisements) and
content (articles) to appeal to consumers that have been exclusively gleaned
through various data-mining activities.
The media industries process big
data in a dual, interconnected manner:
·
Targeting of consumers (for
advertising by marketers)
·
Data-capture
Thus, the Internet of things
creates an opportunity to measure, collect and analyze an ever-increasing
variety of behavioral statistics. Cross-correlation of this data could revolutionize
the targeted marketing of products and services.
Environmental monitoring: Environmental monitoring applications of the IoT typically use sensors to assist
in environmental protection by
monitoring air or water
quality, atmospheric or soil
conditions and can even include areas like monitoring the movements of wildlife and their habitats. Development
of resource constrained devices connected to the Internet also means that other
applications like earthquake or tsunami
early-warning systems can also be used by emergency services to provide more
effective aid. IoT devices in this application typically span a large
geographic area and can also be mobile. It has been argued that the
standardization IoT brings to wireless sensing will revolutionize this area.
Infrastructure management: Monitoring
and controlling operations of urban and rural infrastructures like bridges, railway tracks, on- and offshore-
wind-farms is a key application of the IoT. The
IoT infrastructure can be used for monitoring any events or changes in
structural conditions that can compromise safety and increase risk. It can also
be used for scheduling repair and maintenance activities in an efficient
manner, by coordinating tasks between different service providers and users of
these facilities. IoT devices can also be used to control critical
infrastructure like bridges to provide access to ships. Usage of IoT devices
for monitoring and operating infrastructure is likely to improve incident
management and emergency response coordination, and quality of service,
up-times and reduce costs of operation in all infrastructure related areas. Even areas such as waste management
can benefit from automation and optimization that could be brought in by the
IoT.
Manufacturing: The
IoT intelligent systems enable rapid manufacturing of new products, dynamic
response to product demands, and real-time optimization of manufacturing
production and supply chain networks,
by networking machinery, sensors and control systems together.
Digital control systems to
automate process controls, operator tools and service information systems to
optimize plant safety and security are within the purview of the IoT.
Energy management: Integration of sensing and actuation systems, connected to the Internet, is likely to optimize
energy consumption as a whole. It
is expected that IoT devices will be integrated into all forms of energy
consuming devices (switches, power outlets, bulbs, televisions, etc) and be
able to communicate with the utility supply company in order to effectively
balance power
generation and energy usage. Such devices would also offer the
opportunity for users to remotely control their devices, or centrally manage
them via a cloud based interface, and enable advanced functions like scheduling (e.g.,
remotely powering on or off heating systems, controlling ovens, changing
lighting conditions etc.)
Medical and healthcare: IoT devices can be used to enable remote
health monitoring and emergency
notification systems. These health monitoring
devices can range from blood pressure and heart rate monitors to advanced
devices capable of monitoring specialized implants, such as pacemakers, Fitbit
electronic wristbands, or advanced hearing aids. Specialized sensors can also be
equipped within living spaces to monitor the health and general well-being of
senior citizens, while also ensuring that proper treatment is being
administered and assisting people regain lost mobility via therapy as well.
Building and home automation: IoT devices can be used to monitor and control the mechanical,
electrical and electronic systems used in various types of buildings (e.g.,
public and private, industrial, institutions, or residential) in home automation and building automation systems. In this
context, three main areas are being covered in literature:
·
The integration of the internet
with building energy management systems in order to create energy efficient and
IOT driven “smart buildings”.
·
The possible means of real-time
monitoring for reducing energy consumption and monitoring occupant behaviors.
·
The integration of smart devices
in the built environment and how they might be used in future applications
Transportation: The IoT can assist in integration of
communications, control, and information processing across various transportation
systems. Application of the IoT extends to all
aspects of transportation systems (i.e. the vehicle, the infrastructure, and
the driver or user). Dynamic interaction between these components of a
transport system enables inter and intra vehicular communication, smart traffic control, smart parking, electronic
toll collection systems, logistic and fleet
management, vehicle
control, and safety and road assistance.
Enabling
technologies for IoT:
There
are many technologies that enable IoT. Crucial to the field is the network used
to communicate between devices of an IoT installation, a role that several
wireless or wired technologies may fulfill:
Short-range wireless
·
Bluetooth low energy (BLE)
– Specification providing a low power variant to classic Bluetooth with a comparable communication
range.
·

So
with all this greatness there must be a catch, true?
Platform
fragmentation: lack of technical
standards a situation where the variety of IoT devices, in terms of
both hardware variations and differences in the software running on them, makes
the task of developing applications that work consistently between different
inconsistent technology ecosystems hard. Customers
may be hesitant to bet their IoT future on a proprietary
software or hardware devices that uses proprietary protocols that may fade or become difficult to customize and
interconnect.
The biggest issue about
IoT is the security part, I will discuss this topic in my upcoming article but
for now I will give the headlines to keep you in the loop:
Privacy threats are
enormous, as is the potential for social control and political manipulation, some
claims that these technologies are not only an invasion of public space but are
also being used to perpetuate normative behavior, citing an instance of
billboards with hidden cameras that tracked the demographics of passersby who
stopped to read the advertisement. The privacy of households could be
compromised by solely analyzing smart home network traffic patterns without
dissecting the contents of encrypted application data, yet a synthetic packet
injection scheme can be used to safely overcome such invasion of privacy.
At the end all of your info will be collected and ad companies will even make
more money tailoring ads for you. Concerns have been raised that the Internet
of things is being developed rapidly without appropriate consideration of the
profound security challenges involved and
the regulatory changes that might be necessary. Most of the technical
security issues are similar to those of conventional servers, workstations and
smartphones, but the firewall, security update and anti-malware systems used
for those are generally unsuitable for the much smaller, less capable, IoT devices.
And let’s not forget the data storage issue, the storage of this bulk data.
Depending on the application there could be high data acquisition requirements
which in turn lead to high storage requirements.
In the end there is no
escape that internet of things is the new hot topic in the world and everything
leads that it’s the next big thing in the technology sector since researchers’ estimates
that more than 30 billion devices will be wireless connected to the Internet
of things by 2020.
