INTERNET BLACKOUT SURVIVAL SYSTEM

The Internet Blackout Survival System is a decentralized communication platform designed to enable communication during internet outages, natural disasters, or network failures. The system operates without relying on traditional infrastructure such as cellular networks or centralized servers. Instead, it utilizes peer-to-peer communication technologies like Wi-Fi Direct and Bluetooth Low Energy (BLE) to form a resilient mesh network. The platform allows users to send messages, broadcast emergency alerts (SOS), and share critical information across nearby devices. It incorporates secure communication using encryption techniques such as Elliptic Curve Diffie-Hellman (ECDH) for key exchange and AES encryption for data transmission. The system ensures reliability through multi-layer communication, where BLE acts as a fallback mechanism when Wi-Fi Direct is unavailable. The application is built using modern Android technologies such as Jetpack Compose for UI, MVVM architecture for state management, and Room Database for offline storage. The system also includes intelligent routing, message propagation control, and real-time synchronization across devices. This platform is highly useful in disaster scenarios, remote areas, and situations where internet access is restricted or unavailable, providing a reliable and secure communication alternative.
