                          What is IoT?
Several definitions used by different groups:
 Internet Architecture Board’s (IAB): IoT is the networking of smart objects,
  meaning a huge number of devices intelligently communicating in the presence of
  internet protocol that cannot be directly operated by human beings but exist as
  components in buildings, vehicles or the environment.
 Internet Engineering Task Force (IETF) organization’s: IoT is the networking of
  smart objects in which smart objects have some constraints such as limited
  bandwidth, power, and processing accessibility for achieving interoperability among
  smart objects.

                        …What is IoT?
Several definitions used by different groups:
 Oxfdictionary’s: IoT is the interaction of everyday object’s computing devices
  through the Internet that enables the sending and receiving of useful data.
 IEEE Communications category magazine: IoT is a framework of all things that
  have a representation in the presence of the internet in such a way that new
  applications and services enable the interaction in the physical and virtual world in
  the form of Machine-to Machine (M2M) communication in the cloud.

                          …What is IoT?
IoT according to 2020 conceptual framework is expressed through a simple
 formula such as:
                 IoT = Services + Data + Networks + Sensors
Generally, The Internet of Things (IoT) is the network of physical objects or
 "things" embedded with electronics, software, sensors, and network
 connectivity, which enables these objects to collect and exchange data.

               Most important features of IoT
AI makes virtually anything
 “smart”,
Connectivity  creates these small
 networks between its system devices.
Sensors  transform IoT from a
 standard passive network of devices
 into an active system capable of real-
 world integration.
Active engagement introduces a
 new paradigm for active content,
 product, or service engagement.          Source: internet

                           History of IoT?
Telegraph (the first landline) - 1830s
“wireless telegraphy,” the first radio voice transmission - June 3, 1900
Computers development - 1950s.
The Internet, by DARPA (Defense Advanced Research Projects Agency) in
 1962 and evolved into ARPANET in 1969 – commercialized in 1980s.
Global Positioning Satellites (GPS) - 1993, by the Department of Defense
The first examples of an Internet of Things is in the early 1980s and was a
 Coca Cola machine, located at the Carnegie Melon University .
Kevin Ashton, the Executive Director of Auto-ID Labs at MIT, was the first to
 describe the Internet of Things, during his 1999 speech.
2013, the Internet of Things had evolved into a system using multiple
 technologies

                        Challenges of IoT?
Security  users can be exposed to various attackers or hackers
Privacy  make substantial personal data in extreme detail without the user's
 active participation
Complexity  complication in terms of design, deployment, and maintenance
 given their use of multiple technologies
Flexibility  difficulty to integrate easily with another system.
Compliance  challenging issue of compliance

                      How does IoT works?
An IoT ecosystem consist:
A. Web-enabled smart devices that use embedded processors and connected to
   sensors, actuators and internet,
B. Sensors to collect data from the environment and send it back to the end
   smart deice for analyzation
C. Communication protocols used by the smart device to send data to the cloud
   to be analyze and provide remote access
The devices do most of the work without human intervention, although people
can interact with the devices.

                           Architecture of IoT
An IoT device consists:
   Hardware,
   Software,
   Network connectivity, and
   Sensors.
Hence, the architecture of IoT comprises:
   Sensing layer,
   Network layer,
   Data processing layer, and

 network as well as the status and characteristics of this network.
IoT network management structure scopes:
   local management, where the platform runs in the same environment as the devices,
   remote management, where the platform controls the devices in different networks.
IoT minimum network requirements
