Turns Every Smartphone into a Beacon

AnchorMesh is a disaster relief mesh network application that turns smartphones into rescue beacons when traditional communication infrastructure fails. Built for the Alameda County Hackathon 2025.

During natural disasters like earthquakes, hurricanes, and wildfires, cell towers often go down first—leaving people unable to call for help when they need it most. AnchorMesh solves this by creating a peer-to-peer mesh network using Bluetooth Low Energy (BLE), allowing SOS signals to hop from phone to phone until they reach someone with internet connectivity.

1. Disaster Detected - The app monitors official alerts and activates automatically when emergencies are detected
2. Mesh Activates - Your phone starts broadcasting via Bluetooth, no internet required
3. People Relay - Nearby phones receive and rebroadcast SOS signals, hopping from person to person
4. Help Arrives - When any phone in the chain finds internet, all SOS alerts upload to rescue teams

• Real-time SOS Dashboard - Monitor incoming emergency signals with priority-based triage
• Live Map Visualization - See alert locations on an interactive Mapbox map
• Mesh Network Relay Tracking - View hop counts and relay chains showing how signals propagated
• Analytics Dashboard - Analyze alert patterns and network statistics
• Disaster Feed - Real-time disaster event monitoring
• Demo Mode - Simulated disaster scenarios for testing and demonstrations
• Alert Sound Notifications - Audio alerts for critical incoming signals

• Framework: Next.js 16 with App Router
• Frontend: React 19, TypeScript
• Styling: Tailwind CSS 4
• Animations: Framer Motion
• Maps: Mapbox GL / react-map-gl
• Backend: Supabase (Auth, Database, Realtime)
• Icons: Lucide React

• Node.js 18+
• npm, yarn, pnpm, or bun
• Supabase account (for backend)
• Mapbox account (for maps)

• Medium - Non-life-threatening emergency
• Low - Status update or relay node
