The Construction of an IOT SystemThe Need of a Network-of-Device Server
1
Important Attributes of the IOT System
1. Devices, or System Building Blocks are
connected via IP Networks.
2. Internet is part of the IP Networks.
3. The number of Connected Devices could be
massive.
4. There is considerable diversity among the
types of Connected Devices.
5. There are intensive interactions among
Connected Devices – in real time manner.
6. More, …

Summary of the Building Blocks
• IP Networks
– Broadband Internet Service
– Local Area Network
• NoD Servers
– System Hardware and Software
– Application Software (NoD
Server Software )
• Cloud Service
• Client Side
– Client Devices
– Client Application Software
• Network Edge Devices
– Sensors
– Actuators
• Gateway Devices
– To Other Systems or Devices

THE NETWORK-OF-DEVICE SERVER -- NOD SERVER, OR IOT SERVER
When more and more NEDs (Sensors and Actuators) are connected to the Local Area Network,
a dedicated NoD Server is needed.
8
The Main Functions of NoD Server
• Management of NED and Clients by Administrator
• Performing 24*7 System Operation
– Real Time
– Heavy Multi-tasking and Multi-thread
– Multi-media information
– Reliable and Scalable
• Providing Client Service
9
Some Issues on IOT Systemsfor High Tech Facilities
• Redundancy for Reliability
• Building Block Approach for Long-term Evolution
• Trend in Big Data and Information Sharing

From NoD to IOT System Platform
• System Platform is an important concept to re-use system building blocks for develop systems of highly complexity.
– Engineers are not able to build every application-specific system from scratch.
• IOT System Platform is needed to build systems for different applications:
– With application specific mix of NEDs
– With application specific Client Application Software.
– With application specific configuration and set-up.
