Data created by PERSONS ➔ data created by THINGS,
uniquely identifiable things with a virtual representation
Heterogeneous objects reveal information about the physical
world, inject it into the virtual world (Internet) where it can be used
as input to services, which can act again upon the physical world.
HYPE?
IoT is not new
Radio-frequency identification• Equip objects with tags, read radio
tags, identify and inventory
• First use of IoT (1999)
Machine-to-machine (M2M)
• One device = one SIM card
• One-to-one device-server
communication over operator
managed network
Internet of Things (IoT)• One device = one IP address
• Internet-based device access:
operator = transport network
• Direct interactions, flexible
applications

multiple
communication
technologies

IoT will be big: how big?
"Economic value-add (through the sale and
usage of IoT technology) is forecast to be
$1.9 trillion across sectors in 2020.

Deployment &
operation?
Plug & play•Easy deployment (auto-configuration, assisted using e.g. wearable
technologies…)
•Self-management, self-diagnostics
•Robustness at scale (e.g. reliable wireless connectivity)
Distributed intelligence to handle huge amounts of traffic

Security – privacy – data protection
Technological aspect:
security protocols exist / are being designed• E.g. IETF is very active on security for constrained devices
• Open challenges: deal with limited capabilities, devices can
be lost/stolen/sold/have finite life, scale, across systems
Human/legal aspect• Apply security solutions
(e.g. default router password)
• How to control your data
(e.g. Facebook data)
Turning data into knowledge
CoAP-enabled sensors
Tagging + semantics
Reasoning on sensor and other data
