3 Internet of Things (IoT) Web of Objects connectivity + reality + intelligence Web-based (RESTful API, Search, Composite, Mashups) Internet of Things (Smart environments) Internet of Clouds (Computing technologies) Internet 3

4 Complexity / Value Towards Smart Objects Real-time localization on item level Protection of trademarks Terrorism combat Event management (VIP, Ticketing) Intelligent clothes epc* Objects Seamless realtime material and process control Documentation of total product lifecycles Permanent inventory Data Objects Temperature monitoring of food Tire pressure Indoor location sensing Optical inventory tags with photo sensors Sensing Objects Signaling of useby date Automatic re-order process and pricing Alert for health risk Advanced announcement of delivery goods Acting Objects Pervasive computing Wearable computing Smart dust Object-to-Object ( (O2O) communication Situation / Localization based services Interacting Objects * electronic Product Code Sources: Siemens CT / STA / CD S, Mitsubishi Electric Research time 4

5 Key technical issues for IoT A world-wide network of uniquely addressable and interconnected objects, based on standard communication protocols. Physical entities (end points) + Object identities = enabler for smart environment Identifying things Object IDs + Security/Privacy Connecting smart things Naming and addressing using object IDs and naming system Mobile environments Resolve object ID with locator due to change of location Heterogeneous interfaces No TCP/IP support 5

6 What are possible solutions? Find possible solutions from HIP Why only for hosts New concept of end points not always humans but may be objects such as devices/machines, and then expanding to small objects and parts of objects Mapping/binding with object identifier Thing/location/application Relationship with ID/Loc separation Host ID and locator + Extensible to object ID Privacy security Security association for air interfaces 6

7 Related activities in IETF/IRTF Low power consumption 6LoWPAN (IPv6 header compression) ROLL (IPv6 routing for low power/lossy networks) 6LoWApp BoF (Low power applications) CORE (Constrained RESTful Environments WG) Architectural issues HIPRG (Host identity protocol research group) RRG (Routing research group) New work items Smart Grid (bar BoF meeting at 76 th IETF) Internet of Things (bar BoF meeting at 77 th IETF) Other GRO BoF (Generic Referral Objects) XMPP 7

8 New work items for IoT Framework Understanding of IoT in the viewpoint of IETF Clear scope of IoT work Architecture for IoT Naming and addressing to support IoT Resolving Object ID and locator Solution spaces Object identity protocol and ONS (object naming service) Protocols for Web of objects Protocol solutions for Web-based 8

9 Discussion on future directions Proposal #1 Development of relevant solutions as the extension of HIP in HIPRG Adopt current documents as RG items Proposal #2 Create a new RG for IoT Other Investigate architectural issues New inputs from relevant work groups of IRTF Find another possible way 9

12 Ubiquitous connectivity Ubiquitous Computing + Ubiquitous Connectivity Internet of Things Web of Things ITU-T Y.2002 Ubiquitous Networking Object to Object communications 12

13 The concept of object Objects include terminal devices (e.g. used by a person to access the network such as mobile phones, Personal computers, etc), remote monitoring devices (e.g. cameras, sensors, etc), information devices (e.g. content delivery server), products, contents, and resources. 13

14 Ubiquitous connectivity vs. object How to identify object to provide connecting to anything To develop object identity protocol Objects Human Personal Devices PC, Phone, PDA, TV, Camera Contents Audio, Video, Doc, Book Info. Devices Server, Database, Navigation, Meter Appliances Home, Office, Medical, Surveillance Providing connectivity Internet RFID/Sensors RFID tag, e-tag, Smart card Transportation Car, Train, Airplane 14

15 Layered architecture for identity processing Identity Processing Identifiers User Name (Attributes) Logical identities for services Web of Things Object IDs (Physical & logical IDs) Identification/ Authorization Mapping/ Binding RFID, Content ID, Telephone number, URL/URI, etc Session/Protocol ID Unique identifier for object Internet of Things Communication IDs IP address MAC address identifier s for networking 15

16 Conceptual diagram for providing connectivity to objects Consider relationship between host and object Host (e.g., server) Object (e.g., content) IP address Object (e.g., device, product, sensor, etc) Internet non-ip interface Gateway IP address IP interface Identifier for object Mapping Binding IP Address Global Connectivity with Internet 16

17 Object mapping extension of stack architecture Objects in a host New naming space for object Object ID Host ID IP address Use object ID instead of Host ID Object ID IP address Security association with IP address Object ID Host ID (Optional) IP address Network attachment IP interface (a) Direct mapping (Objects in a host) 17

18 Object mapping extension of stack architecture Remote objects How to associate Host with IP address and Object with air interface IP address remote object ID Security association Host ID (Optional) IP address Network attachment Object ID Non-IP interface (e.g., air interface) IP interface (b) Indirect mapping (remote objects) 18
