IOT 에 관한 통계 및 시장규모 예측
IDC forecasts 15 billion devices by the year 2015"
ABI Research’s study, “Wireless Sensor Networks,” analyzes
IEEE 802.15.4 and which standards, such as ZigBee, Wireless
HART, and ISA100.11a, will influence and drive the market, as
well as emerging technology and competitive solutions such as
Z-Wave, 6LoWPAN, Bluetooth Smart, and Low Power Wi-Fi.
850 Million IEEE 802.15.4 Chipsets to
Ship in 2016, Despite Strong
Competition from Bluetooth
More than 80 % of decision makers in worldwide companies plan to
implement an IoT solution and 15% already have it.

Everyday objects in the Internet of Things
“Machine-generated sensor data will be
become a far larger portion of the Big Data
world, according to a recent report by
IDC. The research report, “The Digital
Universe in 2020,” published in December,
traces data trends from 2005-20. One of its
forecasts is that machine-generated
data will increase to 42 percent of
all data by 2020, up from 11
percent in 2005.”

Oliot stems from GS1/EPCglobal Standards (Open Language for Internet of Things)
ONS (Object Name System)
- Internet of Things Naming Services
• ONS
– Service to look up information about GS1 Identification keys using standard Domain Name
System (DNS) protocols
• Reason for using DNS
– GS1 standards leverage existing
standards and infrastructure
• Adherence to DNS standards
– GS1 Identification Key must be converted
to DNS compatible domain name
– Results must be a valid DNS resource record

ONS Query response
• ONS Query for ONS Query Responses for the domain name
• ONS Query Response contains a set of Naming Authority PoinTeR (NAPTR) Records
Federated ONS
- Delegation
• Nameserver (NS) delegation
– Information of the related name servers exists below current ONS Peer Root
Ex) 1.4.1.4.1.6.0.gtin.gs1.id.onsepc.com. IN NS ns1.corp.example.com.
• Delegation name (DNAME) delegation
– Information of the related name servers exists in another ONS Peer Root, not current ONS Peer
Root
– Using the GS1 prefix (last three digits), identify where the query is destined.
Ex) 1.6.0.gtin.gs1.id.onsepc.kr IN DNAME 1.6.0.gtin.gs1.id.onsepc.com.
