  • Self-Hosting Internet Gateway:

    MOSA allows you to host your own Internet Gateway, giving you full control over the bridge between the mesh network and the internet.

    Requirements:
    • Linux server (Ubuntu 22.04+ recommended)
    • PHP 8.1+
    • MySQL 8.0+ or PostgreSQL
    • SSL certificate (Let's Encrypt)
    • Domain name (optional but recommended)

    Setup Steps:
    1. Clone the Internet Gateway repository
    2. Install dependencies (PHP, MySQL, Nginx)
    3. Configure database and settings
    4. Set up SSL certificate
    5. Configure firewall rules
    6. Start the gateway service

    Documentation:
    • Full installation guide: docs/09_Internet_Gateway/gateway_installation_guide.md
    • Deployment guide: docs/12_Deployment/PRODUCTION_DEPLOYMENT_GUIDE.md
    • Security guide: docs/09_Internet_Gateway/gateway_security_guide.md

    Benefits:
    • Full control over your gateway
    • No reliance on third-party services
    • Custom configuration
    • Enhanced privacy

    Note: You can also use the official Talivio Gateway at gateway.talivio.com
  • ACFR Algorithm:

    The Adaptive Congestion-Free Routing (ACFR) algorithm is MOSA's proprietary routing solution that prevents network congestion even under heavy load.

    How It Works:
    • Each node monitors local network congestion
    • Emergency packets get priority
    • Low-priority packets are randomly delayed
    • Alternative routes are calculated to avoid congested areas
    • Trust scores prevent malicious nodes from disrupting the network

    Benefits:
    • Network remains functional under heavy load
    • Emergency messages always get through
    • Automatic route optimization
    • Self-healing network topology

    Technical Details:
    • See: docs/02_Architecture/network_protocol.md
    • Performance metrics: docs/02_Architecture/performance_metrics.md
  • Protocol Comparison:

    BLE Mesh:
    • Range: 30-50 meters
    • Speed: 10-30 KB/s
    • Power: Low
    • Use: Short-range, no gateway needed
    • Features: Text, location, reactions

    LoRa:
    • Range: 1-5 km (urban), 5-15 km (open)
    • Speed: 0.3-5.5 KB/s
    • Power: Very low
    • Use: Long-range text, location
    • Features: Text, location only

    FSK:
    • Range: 300m-1km (urban), 1-3km (open)
    • Speed: 100-300 KB/s
    • Power: Medium
    • Use: Voice, media, high-speed data
    • Features: Full features including voice and media

    Choosing the Right Protocol:
    • BLE: For close-range communication
    • LoRa: For long-range text messaging
    • FSK: For voice calls and media sharing

Frequently Asked Questions

Common questions about MOSA

MOSA (Mesh Offline Secure Architecture) is a military-grade secure offline mesh communication system. It allows you to communicate without internet or GSM networks using standard smartphones or Gateway devices.

No! You can start using MOSA with just your smartphone. Gateway devices are optional and extend the range of communication.

MOSA uses mesh networking technology. Your phone connects directly to nearby devices using Bluetooth Low Energy (BLE), LoRa, or FSK protocols. Messages are relayed through the mesh network to reach their destination.

Yes! MOSA uses military-grade encryption (Ed25519, X25519, ChaCha20-Poly1305) with end-to-end encryption. The Zero-Knowledge architecture ensures that even Gateway operators cannot see message content.

MOSA Core is completely free forever with unlimited mesh messaging. Paid plans add bridge features to connect with WhatsApp/Telegram and include media sending and cloud backup.

With just smartphones (BLE Mesh), range is 30-50 meters. With Gateway Lite (LoRa), range extends to 1-5 km. Gateway Pro (FSK) provides 300m-1km range with higher bandwidth.

Yes! MOSA is specifically designed for disaster situations. The ACFR algorithm prevents network congestion even under heavy load, making it ideal for emergency communication.

Beta testing is planned for Q1 2026. Official release is scheduled for Q4 2026.
