6 SCOVARS Applications in Sale of LEGO Toys at Stores Planning and scheduling of production of toys Inventory control of each kind of toys Uses the RFID labels at the toys, packages and containers for shipping 6

7 SCOVARS Applications in Sale of LEGO Toys at Stores As soon as a toy sells at a store the inventory auto adjusts Reordering triggers for the toys sold during a week An app for automated reordering at customer-end Reordering event initiates processes at a server Event messages route to the ERP applications at the LEGO enterprise 7

8 Design Steps 1. Abstraction 2. Reference Model 3. Identifying Requirements of Device and Gateway Domain 4. Identifying Requirements of Network Sub-domain 8

9 Design Steps 5. Design Implementation of Device and Gateway Domain Hardware and Software 6. Design Implementation of Application and Network Domain Software 7. Testing and Validation 9

10 Abstraction as a Data Tree of IDs An identity each assigns to a root node (level 0) of a data tree Supply end (SE) assigns identities at daughter datanodes (level 1) for each shipment Shipping node (SN) assigns identities at container data nodes (level 2) 10

11 Abstraction as a Data Tree between PE to POSE Ends Shipping end (SHE) consists of identities of group of containers data nodes (level 3) Sales organisation end (SOE) receiving the group of toy containers consists of identities of containers at data nodes (level 4) Point of sale end (POSE) assigns the identities at leaf nodes 11

12 Abstracted Data Tree Nodes with universal resource identifiers (URIs), messages, alerts and triggers Data nodes are distributed nodes in the PE-POSE supply chain network 12

13 POSE to PE end-to-end Communication Abstraction As communication of events, alerts, triggers, messages and data files Reordering information in a file 13

14 ITU-T four-layers Architecture Reference Model for SCOVARS Abstraction Layer 1: Device layer capabilities and gateway capabilities RFID physical device-cum-rfid reader Identified by URI at each node 14

15 ITU-T four-layers Architecture Reference Model for SCOVARS Abstraction Layer 2: Transport and network capabilities Protocol handlers and Internet connectivity 15

16 ITU-T four-layers Architecture Reference Model for SCOVARS Abstraction Layer 3: Services and application-support layer capabilities at a server node RFID devices URI registry Access management URI management and URI time series Server node database Events processing and data analytics 16

17 ITU-T four-layers Architecture Reference Model for SCOVARS Abstraction Layer 4: Operations, services and applications capabilities Tracking Plan and schedule toys production Schedule deliveries Shipping Order verification Acknowledgement 17

18 Layer 1 Design Implementation of Device and Gateway Domain Hardware and Software Arduino Yun Combines the Arduino-based board with Linux Two processors are ATmega32u4 for support to Arduino and Atheros AR9331 for running Linux. 18

19 Eclipse Kura for the Arduino Yun Kura development environment Gateway Services Cloud connectivity Management of device Network configuration and applications 19

20 Layer 2 Design Implementation of Device and Gateway Domain Hardware and Software Yun IoT applications enablers Wi-Fi, Ethernet support, a USB port, micro-sd card slot, 3 reset buttons and more Yun can be controlled from anywhere with any Internet connected web browser without assigning IP address to board. WebSockets can also be used for providing real time full-duplex communication over TCP.10 20

21 Layer 3 Implementation at a PaaS Use the Connected devices or connected universe platform Access management Server node database Events processing and Data analytics 21

22 Layer 4 Implementation of Operations, Services and Applications Use the Connected devices or connected universe platform 22

23 Testing and Validation Arduino IDE open source and provides embedded hardware and software platform, simulating, and debugging Implanted hardware/software at each end-point between POSE and PE Thoroughly tested in the laboratory environment 23

24 Summary We learnt SCOVARS design process and prototype development Steps abstraction, design of hardware and software in ITU-T 4 layers reference model Arduino board suits prototype RFIDs at the customer and company ends Arduino IDE and tools enable programming 24

25 Summary We learnt Soft serial Library for reading an RFID tag or using a program for sending data to USB port for onward transmission on Internet. Implementation of the design for the hardware and software using the IDE and Eclipse Kura module Testing and validation 25
