11. Edge Processing Requirement
▪ Why Edge Processing?
• Huge amount of devices and data
□ Heavy occupancy of bandwidth
□ Increase of latency time
□ Decrease of processing efficiency
• Specific environments
□ Unreliable connection environment
□ Real-time environment
□ Private environment
▪ Key Functions:
□ Communication over protocols
□ Data normalization
□ Keep data persistence
□ Notifications
□ Data visualization
□ Connection and synchronization with
remote/centralized cloud
□ Device/Gateway management
□ Security
▪ Advantages:
□ Real time processing
□ Increase service availability
(cloud independent)
□ Lighten cloud
□ Bandwidth optimization
□ Cost optimization
(Internet connection via or SIM)

12. Edge Processing in WAZIUP: Local Cloud
▪ Light-weight IoT PaaS at gateway-level for computing and application
• Raspberry PI Gateway (Kura) for data normalization
• Local Cloud with data storage and key functions
• Ongoing development
Local
Cloud

13. Device and Gateway Management Requirement
▪ The management of devices and gateways is indispensable in IoT world. Why?
• IoT not “fire and forget”, need bug fixes and software updates
• Scalable automation of routine tasks: communication and control of a list of devices
• Alert and remote diagnostic in case of malfunction
▪ Gateway Management
• Provisioning
• Configuration
• Software Management
• Command Execution
• Monitoring
• Diagnostic
• Management of connected devices
▪ Device Management
• Provisioning
• Configuration
• Software Management
• Command Execution
• Monitoring
• Diagnostic

14. Device and Gateway Management in WAZIUP: Gateway Manager
▪ Goal: to minimize the deployment and configuration effort on the gateway side
▪ Ongoing development with simple functions
• Data Interface: REST API and SMS from gateway to Cloud
• Deployment and Data Transfer: automatic association of gateway data with services and owners info
on cloud side.
• Claiming sensors
• Sensor data calibration
▪ Ongoing investigation of LWM2M
