Hello, Ciao, Grüetzi…
IoT needs standards Too many standards means no standard Big companies grouped in consortiums Communication protocols must meet
low-bandwidth requirements Interoperability at server level is not
always the best solution

야심찬 신제품이 시장서 실패하는 이유
“기업은 소비자들이 신제품의 새로운 효용에 매료될 것이라고 생각하지만 실제로 소비자들은 가격이 적절한지, 기존 소비 습관을 바꿀만한 것인지, 사회적행동의 변화를 가져올만한 것인지 등 심리적 요인에 영향을 받는다. 이 때문에소비자의 구매를 유도하기 위해서는 다각도로 소비자 심리에 접근해야 한다.”

IoT Scenario

Consideration 2: Next Web Application ?
21
Evolution of World Wide Web
22
But , Web Technology for Small Connected Things ?
Half of connected devices will be small IoT devices(how we can bring those devices into the web ecosystem)
We need to consider these small devices
23
Characteristics of Small Connected Thing
Connectivity Locally, Globally Wired, Wireless
Controllability One way, Two way Immediately, …
Interactivity Interaction ability – screen, sound, light …
Limitations Low Computing power Device capability Non-screen

Traditional Web Architecture
WebResources
URI/IRI
RESTful
Web Connectivity
Presentation purpose(for human interaction)
25
Simple WoT Architecture
WebResources
RESTful
Smalldevice
Smalldevice
What kind of request ?What kind of response ?Do we need to use HTML/CSS markup ? which kind of web client do we need ?
Web Connectivity
Control purpose(for automatize interaction)
Client/Server Client/Server

Web Architecture for Non-screen Devices
Absence of Presentation Layer
