Review of IoT activities in ITU

• ITU’s study on future networks , M2M , and IMT-2020 instrumental for IoT

• ITU-T Y.2060 (2012) Overview of the IoT

– Thing – an object of the physical world (physical thing) or the information world (virtual thing), which is capable of being identified and integrated into communication networks

– Device – a piece of equipment with the mandatory capabilities of communications and the optional capabilities of sensing, actuation, data capture, storage, and processing

– IoT – a global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies

– Adding fourth dimension of anything (besides anyplace, anytime, anybody) to communication

ITU-T IoT-GSI and SG20

• ITU-T IoT-GSI

– Providing common platform for experts from various

SGs (e.g. SG2, SG3, SG9, SG11, SG13, SG16, SG17)

– Promoting collaboration with SDOs to harmonize approaches to unified IoT standards development worldwide

• ITU-T SG20 established in 2015 June

– “IoT and its applications including smart cities and communities”

– Exclusive studies of IoT technologies, services and applications in a single place



8/21

Requirements of IoT

• ITU-T Y.2066 specifies non-functional and functional requirements

– Non-functional: related with implementation and operation

– Functional: applications support, service, communication, devices, data management, etc.

• However, lacking technological requirements of IoT infrastructure

Y.2066

9/21

Requirements of IoT infrastructure

• Sharable

• Trustable and reliable

• Service-aware, data-aware, user-centric

• Scalable naming, numbering, identification

• Location-independent heterogeneous communication

• Open and standard APIs



10/21

Prospective technologies

• Software-defined networking

• Security and privacy protection

• Network softwarization and information-centric networking

• Mobile edge computing

• Naming and identification schemes

• ID-based communication

– e.g. automated driving

• Reduces data volume transaction

• Lightens end user device functionality

– Enabling economically and technologically massive deployment



15/21

New naming and identification scheme

•

• IDs assigned to various things – devices, data or content, users, services, and others

(e.g. application software, storage or computing resources)

Trust, security, privacy

• Five dimensions of trust: availability, reliability, performance, security, privacy

• Three domains in IoT trust:

1. Platform

– Generic and service specific functionality

• e.g., hiding identity in private/personal data

2. Network

– Encrypted pipe

– Location privacy

3. Storage or cloud

– Several issues as discussed in previous sessions
