2. Cloudscape presentation 2
Use Cases: Expand 5G on Remote Areas

3. Cloudscape presentation 3
• ETSI NFV Model
• Used by 5G-PPP Projects
o 5Gcar, NRG-5, 5G 5G-
MoNArch, etc
• Open Source MANO
o Orchestrator
• OpenStack
o VIM
• Raspberry Pi 3B/3B+/Zero
Network Function Virtualisation

4. Cloudscape presentation 4
Interfaces Requirements
Objective:
 Deploy long range (10-15 km) and low energy consumption virtual infrastructure control communication for power constrained devices
VIM Communication (Control)
VNF Communication
In-band

5. Cloudscape presentation 5
Control Plane Data Characterisation
• Principal Factors:
o Long distances
o Small control messages
o Power Efficiency
Mini-ITX
RPi
~~
Approach:
 Use of emerging Low-Power Wide Area technologies such as LoRa

Preliminary Experimentation: Results
Throughput(Bits/s)
Total Throughput
- Peak: 3.99 kbps
- Median: 0,35 kbps
- Peak Median
• Min: 1.36 kbps
• Max: 1.64 kbps
- 5378 requests on 20 min
- 4.5 requests per second
First Impression
- Low Data Rates
- High number of requests
- Periodic peaks

8. Cloudscape presentation 8
• Define Better Samples
o VNF shutdown
o Keep-alive messages
• Run Reliability Tests
• Run Throughput Comparison Tests
o Wi-Fi x LoRa
Next Steps
