Introduction

What is Internet of things?
1. Network of objects .
2. A system to identify any kind of object.
3. From a network of interconnected computers to a network of interconnected objects
6
What is Internet of things?
… from communicating people (Internet) ... to communicating items …
... from 3-5 computers per person … ... to 10-25 communicating items per person …
7
Internet of Things
Characteristics
Pervasive
Ubiquitous
Emerging
Global
8
Internet of Things: pervasive… ubiquitous…
Define: pervasive
Define: ubiquitous
Technology that will be all around us and therefore “invisible”
9
IoT : emerging
Define: emerging
10
IoT : global
11
IoT: components
12
How to identify an object? : RFID example
Supermarket
Producer
Query process in ONS
13
IoT :IP Based
Thanks to IP:
• IP is versatile
• IP is scalable
• IP is ubiquitous
Internet of Things
14
The layered IP architecture
15
IoT : Standard
IEEE 802.15.4 – The New IP Link
1% of 802.11 power easier to embed, as easy to use
16
IoT : middleware system solution Applicatio
n TCP/UDP MAC layer& Physic layer
Adaptation Layer IP/ICMP
6LOWPAN802.15.4
The position of 6LoWPAN in the network architecture
802.15.4 has a maximum frame size of 128 bytes.6lowpan compresses the standard 48 bytes of the IPv6 and UDP headers down to 6 bytes.

IoT network example
18
Challenges of LoWPAN
19
Security in the IoT What do we need?
authentication of tags proof of origin of products
authentication of readers … access control to tag’s data/configuration
encryption … privacysecure point to point connection – data integrity
signatures by tags/objects … mobile readers and static tags
