When Towers Fall, People Stay Connected
Root-Net transforms every smartphone into a resilient communication node. BLE + Wi-Fi Direct form an adaptive, encrypted, delay-tolerant mesh when infrastructure collapses.

The Problem
Infrastructure Fragility in Extreme Environments
When the 7.8 magnitude earthquake struck Turkiye in February 2023, billions of dollars of telecommunications infrastructure became useless at the exact moment it was most required.

Survival Rate vs. Time Post-Disaster
Communication availability is a primary determinant of survival probability
| Time Window | Survival Rate | Operational Reality | Urgency |
|---|---|---|---|
| First 24 Hours | 90% | Local self-organized rescue is primary. | high |
| 24 - 48 Hours | 50-60% | Aid distribution and triage begin. | medium |
| 48 - 72 Hours | 20-30% | Critical window without water/food. | low |
| After 72 Hours | <10% | Recovery replaces rescue as priority. | No rescue |
Protocol Flow
How Root-Net Operates
A packet-level architecture transforming passive smartphones into resilient communication relays.
Device Discovery
Every smartphone becomes a mesh node. BLE continuously scans for nearby peers and exchanges routing metadata.
Store-Carry-Forward
Messages are stored locally and forwarded hop-by-hop.
Predictive Routing
PRoPHET routing selects optimal relay paths using encounter history.
Bridge to Grid
When connectivity is restored, messages burst outward.
Dual Transport Engine
Hybrid Mesh Transport Layer
BLE maintains constant low-power peer discovery. Wi-Fi Direct activates for high-bandwidth burst transfers. Together, they form an adaptive communication engine.
Bluetooth Low Energy
Always-On Discovery Layer
Continuous peer scanning (~100m radius)
Ultra-low battery consumption
AES-128 transport encryption
Wi-Fi Direct (P2P)
High-Bandwidth Burst Layer
Up to 250 Mbps transfer speed
Activated only when required
WPA2 / WPA3 secured sessions
Transport Layer Comparison
| Feature | BLE | Wi-Fi Direct |
|---|---|---|
| Max Range | ~100m (330 ft) | Up to 200m |
| Bandwidth | ~1-2 Mbps | Up to 250 Mbps |
| Power Impact | Minimal | Significant |
| Security | AES-128 | WPA2/WPA3 |
| Primary Use | Peer discovery & packet sync | Media / voice / map transfer |
Cryptographic Hardening
Attack Surface vs Defense Layer
Every threat vector is countered with layered, modern cryptographic safeguards.
Threat Landscape
Message Interception
Unencrypted broadcasts expose sensitive coordination data to hostile listeners.
Impersonation
Lack of authentication enables malicious fake rescue alerts.
Traffic Analysis
State actors can reconstruct social graphs from metadata.
Denial of Service
Malicious packet flooding can disrupt mesh communication.
Defensive Architecture
End-to-End Encryption
Signal-based Double Ratchet ensures forward secrecy.
Noise Protocol Framework
Secure transport encryption across BLE & Wi-Fi Direct.
QR Code Handshakes
Physical verification eliminates MITM attacks.
Anonymity by Default
No phone numbers. Rotating public keys protect identity.
Scaling the Mesh for Real Impact
A unified communication layer across responders, civilians, and infrastructure.
Responders
Long-range radio gateways bridging mesh to command infrastructure.
Civilians
Neighborhood-level SOS broadcasting and coordination.
Infrastructure
Surviving IXPs act as high-bandwidth relays.
SOS Hub Protocol: Fair Relay Rotation
Battery-aware relay logic ensures even 5% devices remain connected for the 72-hour golden survival window.
