What is still needed for the Web Of ThingsInterconnection of WoT “islands”Vendor discoveryIncentives why you should share your data
Beginning 2011 @TecO we wanted to: (re-)implement our ubicomp apps on a common platformdeploy our sensors around (still had 500+ unused uparts left…)

Just married……so he cannot be here today
Research visit to Jan-March 2011His previous work: SensingCloudMost of the stuff you see is implemented by him
Including most slides today

Web-of-Things
A Web-Technology based approach (e.g. RESTful)
Many Research has been done in this field.Web-Based Middleware for Home Entertainment
Daiki Ueno et. al. 2002Efficient Application Integration in IP-Based Sensor Networks
Dogan Yazar et. al. 2009
WoT are often also islandsand even like the of web for documents.
Everybody wants to sell their platform…

Enabling portability of applications:

Our answer:
Keep it simpleKeep it localShare resources

1st step:Local Web-of-Things using uBox
In home, office or school, users should place uBox and create their own Web-of-Things by registering http-based devices.
This enables users to control variety of devices with an unified API.
People create applications privately in a sandbox
uBox@WoT 201113.04.2023 12
uBoxes are interconnected to other uBoxes over P2P network.
Users can connect not only their local devices but also global devices as well from their uBox as an entry point.
People share sensors and applications

Separation of Resource Manager and Global Gateway
This way, you can publish your device data with everything under control.

Why else should I use the uBox?multicast PUT routing
One to many communicationasynchronous communication important for your
http GEThttp PUT eventing via asynchronous http GET (ajax, [webhooks] style)REST emulation on GET only interfacesHTTP cache control
Integrationcan be used together w/ existing stuffSimple REST style discovery and communication proxy
content negotiation (w-i-p)xmljsonhtmlbinary XML (e.g. EXI)
it helps us a lot…

as soon things are reorganized at KeioSoftware release Deployable distribution (vmware_image/app engine/cloud)
