Introduction (2/3)

According to Wikipedia, IoT refers to the interconnection of uniquely

identifiable embedded computing-like devices within the

existing Internet infrastructure.

Typically, IoT is expected to offer advanced connectivity of devices,

systems, and services that goes beyond

machine-to-machine communications

(M2M) and covers a variety of protocols,

domains, and applications.

The interconnection of these embedded

devices (including smart objects), is

expected to usher in automation in

nearly all fields, while also enabling

advanced applications like a Smart Grid.

Introduction (3/3)

Things, in the IoT, can refer to a wide variety of devices such as heart

monitoring implants, bio-chip transponders on farm animals,

automobiles with built-in sensors, or field operation devices that assist

fire-fighters in search and rescue.

Current market examples include smart thermostat systems and

washer/dryers that utilize WiFi for remote monitoring.

Things are expected to become active participants in business,

information and social processes where they are enabled to interact

and communicate among themselves and with the environment by

exchanging data and information ‘sensed’ about the environment, while

reacting autonomously to the ‘real/physical world’s events

Interconnectivity

► Anything can be connected with the global information and communication infrastructure

Things-related services

► IoT is capable of providing thing-related services within the constraints of things: privacy protection and semantic consistency between physical and virtual things

Heterogeneity

► Devices are heterogeneous as based on different hardware platforms and networks

Dynamic changes

► The state of devices as well as the number of devices can change dynamically

Enormous scale

► The number of devices is at least an order of magnitude larger than the devices connected to the current Internet


Why IoT?

Dynamic control of industry and daily life

Improve the resource utilization ratio

Better relationship between human and nature

Forming an intellectual entity by integrating human society

and physical systems

Flexible configuration, PnP…

Universal transport & internetworking

Accessibility & Usability

IoT Enabling Technologies Sensor Technology (1/3)

Sensor technology play a pivotal role in bridging the gap between the

physical and virtual worlds, and enabling things to respond to changes

in their physical environment

Sensors collect data from their environment, generating information

and raising awareness about context

► Sensors in an electronic jacket collects information of changes in external temperature and the parameters of the jacket are adjusted accordingly


IoT Enabling TechnologiesSensor Technology (2/3)

Using sensory data, an MCU in a game platform could detect the

player’s emotions to make the game more exciting.

► How about making turns faster and more difficult to maneuver in a driving

game until the gamer shows a more relaxed state?


IoT Enabling TechnologiesSensor Technology (3/3)

The interactions between human being, nature and environment and

machine/infrastructure provide valuable data for determining context

awareness, including:

► The human being

► The ambient environment

► Infrastructure/machines

being used by the person

(2) When shopping in the market, the

goods will introduce themselves.

(1) When entering the doors, scanners

will identify the tags on her clothing.

(4) When paying for the goods, the

microchip of the credit card will

communicate with checkout reader.

(3) When moving the goods, the reader

will tell the staff to put a new one.
