The Internet of Things
The Internet of Things, ITU Report, November 2005
• “Machine-to-machine communications and person-to-computer communications will be extended to things, from everyday household objects to sensors monitoring the movement of the Golden Gate Bridge or detecting earth tremors.Everything from tyres to toothbrushes will fall within communications range, heralding the dawn of a new era.”
“technologies that will drive the future Internet of Things, including radio-frequency identification (RFID), sensor technologies, smart things and nanotechnology and miniaturization”
In the context of• ubiquitous computing• next-generation networks

The Internet of Things• “The vast majority of the one billion of Internet connections
worldwide are devices used directly by humans, such as computers and mobile handsets. But we are entering a new age in which thenumber of "things" connected to the internet will be much largerthan the number of "people". The term "Internet of Things" describes the vision of pervasive and "hidden" computing in whichIP-connected devices will be embedded in the environment allaround us. The key technological drivers behind the Internet ofThings are likely to be radio-frequency identification (RFID), sensors, nanotechnology and intelligent systems.
• The Internet of Things requires us to view cyberspace in a differentway. It is always-connected, responsive, adaptive and, above all, omnipresent in all aspects of our lives. The technology is here, but there is a challenge to build new business models and applications that will exploit the new capabilities.”

Artificial Limbs
• Artificial arms with semi-functional hands, some even fitted with working opposable “thumbs” plus 2 “fingers”, and legs with shock absorbing feet capable of allowing a trained patient to even run, have become available

Embedded Shoes
• Adidas produced microprocessor-equipped running shoes, that can adapt to a runner's size, speed and fatigue level.
• At MIT, researchers developed shoes that do everything from providing gait therapy to generating power for wearable electronics.
• Adding embedded intelligence to a running shoe solves a longstanding problem: ever since running gained widespread popularity during the 1970’s, shoe manufacturers have been searching for a way to create an “adaptable shoe” that could provide the appropriate level of cushioning, whether the wearer weighed 50 or 100kg.
• The embedded microprocessor calculates the pressure between the runner's foot and the ground five million times per second and continuously changes the cushioning to match an adjustable comfort level. The computer controls a motor that lengthens and shortens a cable attached to a plastic cushioning element.

• Connectivity: IMPROVING– increasingly wireless– growing slower in some places– with quite distinct grades of service
• broadband varies tremendously• available wireless technologies

Only Tagging?• The tag or transponder, which
contains an electronic circuit (transponder) is attached to the object that requires a unique identification code. When the tag comes near the reader, the radio frequency (RF) field generated by the reader will power up the tag and cause it to continuously transmit its data by 'pulsing' the radio frequency. The data is then captured by the reader and processed in the back-end by applications like the Enterprise Resource Planning (ERP) or Supply Chain Management systems.

Dr. Jorge Pereira, EC ERCIM eMobility Workshop23
Challenges 2: Scalability
SCALABILITYCurrent deployments number in the hundred(s)…
…we are aiming at hundred(s) of thousands!
is not trivial!
Dr. Jorge Pereira, EC ERCIM eMobility Workshop24
Challenges 3: Cooperation
• From autonomous (independently operating) to cooperating smart (Monitoring and Control) systems
• Making the most of Heterogeneity and “diversity” in order to improve whatever optimisation is at stake

Dr. Jorge Pereira, EC ERCIM eMobility Workshop25
Challenges 4: Connectivity
What Connectivity?• Their level of connectivity will vary
tremendously, the same with their requirements
• Most of the traffic will be “peer-to-peer”and remain rather local

Trends 4
• Embedded Intelligence: PERVASIVE + NETWORKED!!!

Nike iPod Sports Kit
• The wireless kit lets Nike's new Air Zoom Moire shoes send fitness data to the iPod Nano - via a sensor tuck inside the running shoe and a small receiver that attaches to the Nano.
• As you run, the sensor records your distance, time, pace and calories burned in real time and displays data on the Nano. At the push of a button, audio feedback is delivered through Nano's earbuds.

Conclusion 1• Embedded systems are becoming ever more pervasive,
permeating all things and everything:– from (home) appliances– to all sorts of electronic equipment/consumer electronics (videos,
cameras, HiFi)– to vehicles (cars, trains, ships, airplanes)– to industrial, scientific and medical equipment (motor drivers,
monitors)• Miniaturisation (micro-systems, micro and nano-
electronics) and development tools (middleware) andsystem management tools makes them cheaper, easier to integrate, and even more pervasive, infiltrating ever more segments of the economy.
Dr. Jorge Pereira, EC ERCIM eMobility Workshop30
Conclusion 2
• As all this smart things become even smarter, they incorporate enhanced sensing/monitoring and actuation capabilities and are getting increasingly networked. At that stage, the next step can be taken, that of moving from autonomous (non-networked, thus individual) to cooperative (networked, local to global) optimisation/operation/control, and also from homogeneous to heterogeneous sensing/monitoring and control.
• As systems and processes become ever more complex and of increasing scale, this networked heterogeneity(and the ensuing data fusion, modelling, inference and decision making) is the only means to address the control problems that arise across the economy/society.

Dr. Jorge Pereira, EC ERCIM eMobility Workshop31
Conclusion 3
• In the end, we are talking of smart, networked (mostly wireless) heterogeneous sensors/actuators embedded in everything, for a purpose: optimising the performance of equipment and/or processes by enhancing control
• The tremendous potential of the ensuing Internet of SmartSmart Things is that one can go beyond the “blind” individual, ad hoc optimisation of device performance/elemental processes, to a rather more “all encompassing”end-to-end optimisation of the overarching processes/organisations via cooperation
