How can devices connect and work?  Each device is connected with individual protocol for each purpose.

- DLNA: connects TV set and video recorder - ECHONET Lite/KNX: connects smart phone and home appliances - Propriety protocol: connects devices do NOT support standard

Issues on device connection  Users want to use several applications by one device  Need to introduce Platform should support  Wide variety of device interfaces / protocols  Keeping devices connections stable in area network

Wide variety of device interfaces  Platform must absorb interface gap between devices and applications  Device interfaces have many transport protocol and data formats  Application interface is Web interface, so simple for developers Ethernet, Wi-Fi Bluetooth, RS-485/232C, …

Standard architecture (ITU-T Y.2070)

Y.2070: Requirements and architecture of home energy management system and home network services

 Overview

 Architecture to monitor and control devices connected in local network through gateway from cloud  This architecture simplified to 3 ways for connection between gateway and devices in area networks

 Features

 Common application interface for operation to various devices  Cover various interfaces of devices with simple ways  Easy to detect problems happened in area networks

Web of Things (WoT)  Detail specification for device abstraction and operation is discussed in W3C Web of Things Interest Group.  Physical devices are described as a set of properties in abstract.  Each property corresponds to the functions of physical devices

 Initial recommendation will be completed in 2018

 Siemens, Panasonic, Intel, Fujitsu, and many companies joined. Physical devices Standard device

Keeping device connection stable  Operated networks (ex. LTE) CAN remotely recognize

 places to use with terminals.  the current status, such that each of them cannot accept the call.

 Area network CANNOT remotely recognize  places to use with IoT devices.  topology of networks and connected devices.  fault occurring in networks and devices.

Management for area network  Customer supports want to know

(1) devices connected (2) network topology, and (3) fault occurred

 Obtain what devices connected to network are

 Get it directly using standard protocols such as DLNA, ECHONET Lite, UPnP, …

 Recognize current network topology frequently changed  Collect information of neighbor devices using standard protocol.

 Detect fault occurred and identify where it did

EX. ITU-T G.9973

 Get running status of networks and devices and analyze them Home appliances Device information

Running status on wireless networks  Many devices connected with family of IEEE standards, however most of them do NOT notice their status.  Difficult to know troubles occurred in area networks.  IEEE 802.1CF specifies common interfaces for each IEEE standards should have.

Conclusion and Next step  These standards do NOT intend to dictate every system  They provide just framework for Web of Things.  Concrete definitions of vocabulary for properties should be specified in some organizations.

 Smart city/IoT business has two aspects of cooperative and competitive.  Standard is one of starting points for cooperative works.

 Fujitsu supports customers to setup and operate smart city applications and systems including IoT devices.

 SSPF: Software for device abstraction and management had been launched in 2011, compatible to Y.2070.  IoT platform: Cloud service for IoT applications had started in 2015.  We continue to support Web of Things related standardization to build up ecosystem with partners. 12
