This document discusses the Internet of Things (IoT) and the related Web of Things (WoT). It notes that an increasing number of "things" are connecting to the internet, with Cisco predicting 25 billion connected devices by 2015 and 50 billion by 2020. However, connecting small devices poses challenges as they have limitations in terms of computing power, capabilities, and lack of screens. The document proposes a simple WoT architecture to control these small connected things through the web in an automated way without traditional presentation layers, as these devices are meant for control rather than human interaction. It concludes by noting open questions around how to request and respond from such devices over the web given their constraints.

Changes - Connected Things
More things are connecting to the Internet than people — Cisco’s Internet
Business Solutions Group (IBSG) predicts some 25 billion devices will be
connected by 2015, and 50 billion by 2020

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 실
제로 소비자들은 가격이 적절한지, 기존 소비 습관을 바꿀만한 것인지, 사회적
행동의 변화를 가져올만한 것인지 등 심리적 요인에 영향을 받는다. 이 때문에
소비자의 구매를 유도하기 위해서는 다각도로 소비자 심리에 접근해야 한다.”

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
