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 …

Internet of Things: pervasive… ubiquitous…

Define: pervasive

Define: ubiquitous

Technology that will be all around us and therefore “invisible”

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.

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
