What is Mesh Networking?
A network topology where devices connect directly to each other without relying on centralized infrastructure, enabling censorship-resistant communication.
Mesh networks allow devices to communicate by relaying data through each other, creating a decentralized network that doesn't depend on ISPs or cell towers.
Privacy Benefits
- No central point of control or surveillance
- Communication can work even when the internet is shut down
- Traffic routes dynamically, making interception harder
Use Cases
- Protest communication: When authorities shut down cell networks
- Disaster recovery: Communication when infrastructure is destroyed
- Rural connectivity: Extending internet access to remote areas
Tools
- Briar: Encrypted messenger that works over WiFi, Bluetooth, and Tor
- Meshtastic: Long-range mesh networking using LoRa radios
- Yggdrasil: Encrypted mesh networking protocol
Limitations
- Limited range between nodes
- Performance degrades with distance
- Requires critical mass of users to be useful

I2P
The Invisible Internet Project is an anonymous network layer designed for internal services (eepsites) rather than accessing the regular internet. I2P uses garlic routing to provide strong anonymity for both users and services.
Tor Network
A free, open-source software and network that enables anonymous communication by directing Internet traffic through a worldwide volunteer overlay network of thousands of relays. Tor conceals users' locations and usage from surveillance and traffic analysis.
