The Internet of Things (IoT) is aimed at enabling the interconnection and integration of

the physical world and the cyber space. It represents the trend of future networking, and leads the

third wave of the IT industry revolution. This seminar provides some background and related

technologies of IoT and discusses the concepts and objectives of IoT. Then, the challenges and

key problems involved in IoT development indicated that we are heading towards a ubiquitous

network society", one in which networks and networked devices are omnipresent. In the future,

everything from tires to toothbrushes will be in communication range, heralding the dawn of a

new era, one in which today's Internet (of data and people) gives way to tomorrow's Internet of

Things.

The concept of Things" in IoT has been generalized to ordinary objects at present, and

the interconnection technology is also extended to all networking technologies, including RFID.

IoT is closely-related to the Internet, mobile communication networks and wireless sensor

networks. They are widely considered as one of the most important infrastructures for promoting

economy development and technology innovation. The developed nations have considered the

development of IoT as one of the future development strategies and put huge investment into it

in order to cultivate new economic growth points. For example, IBM proposed the Smarter

Planet strategy, which obtained positively response from the government of the United States.

the Architecture of Internet of Things", supported bythe National 973 Program.

The traditional Internet is oriented towards person-to-person connection, whereas the

Internet of Things is oriented towards connection of inanimate objects. As such, the Internet of

Things covers a larger range of connections and involves more semantics. Internet and telecom

networks are focused on information transfer, while the Internet of Things is focused on

information services. By combining sensor networks, the Internet, telecom networks, and cloud

computing platforms, the Internet of Things can sense, recognize, affect, and control the physical

world. The physical world can be unified with the virtual world and human perception. This

lecture discusses Internet of Things technology from three perspectives: Ubiquitous information

sensing, ubiquitous network convergence, and intelligent information services. In this part, we

will introduce the technical characteristics of the Internet of Things and sensor networks, the

development background of sensor networks, and key technologies of sensor networks.

Ubiquitous systems have the challenge of implicitly collect relevant information about

entities, and use this information to understand and predict their behavior. This allows the

applications to adapt themselves to the entities, thus avoiding to overflow them with inquires and

information . The analysis of trails, the context-aware history of actions, can further improve

the relevance of information. Ubiquitous computing technologies can be leveraged in

disseminating knowledge and learning in higher education setting. Human computer interface is

already pervasive with the existence of smart gadgets and wireless technologies supported by

numerous technologies and applications. In an education setting, teachers, students, educators,

and curriculum developers combined with ubiquitous devices can take the learning to the next

level century tools for 21st-century learners”.

U-learning is the superset of e-learning and m-learning. U-learning is essentially the

integration of both e-learning and m-learning but extends to pervasive learning environment by

incorporation of ubiquitous devices supported by mobile and ubiquitous computing technologies

including mobile devices such as embedded computer devices such as GPS, RFID tags and

sensors, pads, and badges, and wireless sensor networks.

In other words ubiquitous learning environments, equipped with ubiquitous devices and

exploiting ubiquitous technologies can encourage student’s involvement in the learning process,

without requiring student’s active attention. U-learning can relate learning to the learner’s

situation and increase effectiveness and efficiency of education system.

In the twenty-first century, the impact of wireless and ubiquitous technologies is

changing the way people perceive and interact with the physical world. These communication

paradigms promise to change and redefine, in a reasonably short period of time, the most

common way of our everyday living.

The continuous advances in the field of Wireless Sensor Networks and their direct

application in Smart Spaces are clear examples of it. However, in order for this kind of new

generation infrastructures to have a large-scale dissemination, there are still some open issues to

tackle.

FUTURES:

Power companies read meters through tele-metering systems instead of visiting houses;

doctors remotely monitor the conditions of their patients 24/7 by having the patients use devices

at home instead of requiring the patients to stay at hospital; vehicle-mounted terminals

automatically display the nearest parking space; sensors in smart homes turn off utilities, close

windows, monitor security, and report to homeowners in real time. These are scenarios that only

existed in science fiction previously.

With the coming of age of the Internet of Things, however, they are becoming a

reality.Computing, over the past 50+ years, has gone through two distinct phases: the mainframe

era and the personal computing era. The third phase has begun and you may have not even

noticed – that is the way it is supposed to be.

Ubiquitous means existing or being everywhere at the same time, i.e. constantly

encountered. Ubiquitous computing, or “ubicomp”, as it has been tagged will define the future of

computing.The distinguishing feature of ubicomp will be the lack of interface. Everything will

be controlled by natural actions as opposed to the point-and-click interfaces we have all grown

used to Right now we receive information in two distinct ways: pull or push. “Pull” can be

characterized by a user sitting down at a computer, firing up Google, and searching for specific

information in real-time. “Push” is characterized by receiving filtered information based on user

preferences; much like the personalized text messages on your cell phone informing you of

weather or traffic conditions.When computing becomes ubiquitous you will not need to manually

set preferences. The object you interact with will learn from you and provide information based

on your environment. Temperature, time of day, movement, sound, color and light will all

influence the information you receive. Ubiquitous computing will provide a continuous stream of

information without being distracting and will only provide the information you need at the time.

Everything will become interactive and more importantly, reactive.
