IoT / WoT ?
Internet of Things:

Web of Things:

§  “Uniquely identifiable
objects and their virtual
representations in an
Internet-like structure”

§  “Application architecture
for physical objects”

•  Auto-ID Labs (K. Ashton, S.
Sarma, F. Mattern)

§  How do we connect things
to the Internet?
§  OSI Layer 4 and below
§  Buzz: EPCIS, IPv6 lowpan,

•  D. Guinard, V. Trifa, E.Wilde,
D. Raggett

§  How do we build
applications to sense,
actuate and combine
things?
§  OSI Layer 7 and above :-)
§  Buzz: REST, Social
Networks, semantics,
mashup, etc.

BLE and Android

§  Since Android 4.3
§  Phone cannot (yet, as
of 4.4) act as

§  Several devices are
available:
–  TI Sensor tag ideal for
getting started
=> Android Examples

@EVRYTHNG | @domguinard
iBeacons

§  Not (yet) a standard
Bluetooth profile
=> trickier to catch it from
Android

§  Sort of an active NFC
§  Several iBeacons
providers
