The ‘Internet of Things’, which is sometimes used interchangeably with ‘machine-to-machine’ communication (M2M), is not a new idea, it was coined by Kevin Ashton as early as 1999
The concept was simple but powerful, if all objects in daily life were equipped with identifiers and wireless connectivity, these objects could be communicate with each other and be managed by computers
In a 1999 article for the RFID Journal Ashton wrote:“If we had computers that knew everything there was to know about
things—using data they gathered without any help from us -- we would be able to track and count everything, and greatly reduce
waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best. We need to empower computers with their own means of
gathering information, so they can see, hear and smell the world for themselves, in all its random glory. RFID and sensor technology
enable computers to observe, identify and understand the world—without the limitations of human-entered data.”
At that time:• this vision required major technology improvements• how would we connect everything on the planet? • What type of wireless communications could be built into
devices? • What changes would need to be made to the existing
Internet infrastructure to support billions of new devices communicating?
• What would power these devices?• What must be developed to make the solutions cost
Today, many of these obstacles have been solved:• The size and cost of wireless radios has dropped tremendously• IPv6 allows us to assign a communications address to billions of
devices• Electronics companies are building Wi-Fi and cellular wireless
connectivity into a wide range of devices• ABI Research estimates over five billion wireless chips will ship in
2013• Mobile data coverage has improved significantly with many networks
offering broadband speeds• Battery technology has improved and solar recharging has been built
into numerous devices• There will be billions of objects connecting to the network with the
IoT seeks to merge physical and virtual worlds creating 'smart environments' to improve EU citizens' lives, the European Commission supports IoT innovation and future deployment
IoT represents the next step towards the digitisation of our society and economy, where objects and people are interconnected through communication networks and report about their status and/or the surrounding environment
IoT can also benefit the European economy generating economic growth and employment; according to a recent EU study the market value of the IoT in the EU is expected to exceed one trillion euros in 2020
IoT describes a system where items in the physical world, and sensors within or attached to these items, are connected to the Internet via wireless and wired Internet connections
These sensors can use various types of local area connections such as RFID, NFC, Wi-Fi, Bluetooth, and Zigbee
Sensors can also have wide area connectivity such as GSM, GPRS, 3G, and LTE
sensors for temperature, weather, moisture, and more, all of which can be created by different manufacturers
the Network is the key component, where your sensor’s inputs are digitalized and placed
you see your data displayed in a report or some other visual way. This is any computing device which can provide an end result in a visually attractive way in order to analyze and update your data
“Internet Oriented” represents the Internet and its technologies and it act as a middleware between user and intelligent things and so it’s called as intelligent middleware
“Things Oriented” is known as “Intelligent Things” which represents sensors and actuators which is respond it to stimuli from the environment in a consistent manner
“Semantic Oriented” is known as “Intelligent Process” which represents knowledge based and decision making processes
A WSN is a collection of distributed sensors that monitor physical or environmental conditions, such as temperature, sound, and pressure
Data from each sensor passes through the network node-to-nodes
A WSN node is an embedded system that typically performs a single function (such as measuring temperature or pressure, or turning on a light or a motor)
Wearable technology is vast array of devices that monitor, record and provide feedback on you or your environment
Broadly speaking, you can divide wearables along two lines: • Fitness and environment: fitness bands and watches
and even smart clothes are able to monitor and transmit data on your daily activity levels through step counting, heart rate and temperature
• Health: these wearables monitor crucial health factors like oxygen saturation, heart rate and more, and can communicate any results outside of a programmed range to the patient and to her physician
Using IoT devices like Raspberry-Pi 2 running Windows 10 core, we could connect to the OBD (On-Board Diagnostics) port of the car and tap into intricate vehicle information like: • vehicle speed • fuel consumption• airbag information• engine failure• etc.
These devices are connected to cloud and push data coming from OBD ports as well as other sensors on IoT devices like GPS, accelerometer, gyro sensor etc.
Future smart homes will be conscious about what happens inside a building mainly impacting three aspects: • resource usage (water conservation and energy
consumption)• security • comfort
The goal is to achieve better levels of comfort while cutting overall expenditure
Smart homes address security issues by means of complex security systems for detecting theft, fire or unauthorized entry
Different actors will cooperate in the user’s home:• Internet companies• device manufacturers• telecommunications operators• media service providers • security companies• electricity utility companies• etc.
While the term smart city is still a fuzzy concept, there is general agreement that it is an urban area which creates sustainable development and high quality of life
Giffinger et al.’s model elucidates the characteristics of a smart city, encompassing economy, people, governance, mobility, environment and living
Outperforming in these key areas can be achieved through strong human or social capital and/or ICT infrastructure
An initial business analysis concludes that several sectors/industries will benefit from more digitalized and intelligent cities
As a consequence, companies will reduce their operating expenses (OPEX) and improve their productivity due to tighter integration with enterprise resource planning (ERP) and other systems
Also, maintenance of machinery will be facilitated by connected sensors, allowing for real-time monitoring of the health and performance of the factory equipment
IoT realizes both customer needs and business needs: price comparison of a product; looking for other products of the same quality at lower prices; with shop promotions, giving information not only to customers but also to shops and businesses
Having this information in real time helps enterprises to improve their business and to satisfy customer needs
IoT field application: Smart Energy/Smart Grid (cont.)
A smart meter is an internet-capable device that measures energy, water or natural gas consumption of a building or home
With Smart Energy Metering, not only do technicians not have to come and physically read your meter, you have access personally to your energy usage so you can see what impact your consumption patterns have on your wallet and on the environment
IoT objects are “smart” anything, and that’s essentially because they have their own embedded computers—both hardware and software systems, sensors, and network connectivity
These IoT objects are capable of listening and learning, tracking, communicating, and even predicting behaviors, whether it’s adjusting the temperature of a room when motion detectors sense someone’s home, or generating data about the structure of a bridge to prevent a major disaster
From being able to turn a sprinkler system on when the weather has been dry, to offering a discount on brakes when a car’s brake pad sensor detects it’s time for replacing
