| Abstract: | Contemporary communication infrastructure collapses precisely when it is needed most — during natural disasters, network outages, and connectivity deprived environments. This paper presents Epistle, an offline first peertopeer (P2P) disaster communication system that enables seamless devicetodevice messaging without any dependency on the internet or centralized servers. The system leverages WiFi Direct and Bluetooth technologies to form a self-organizing mobile mesh network, where each Android device simultaneously functions as a sender, receiver, and relay node. A hybrid encryption scheme combining AES symmetric encryption for broadcast messages and RSAAES asymmetric encryption for private communications ensures data confidentiality and integrity throughout. The architecture follows the ModelViewViewModel (MVVM) pattern, enabling modular, scalable, and maintainable code. Experimental results demonstrate successful broadcast messaging, private encrypted chat, GPS based location sharing, photo transmission, emergency SOS broadcasting, and a radar-based peer discovery interface — all operating entirely offline. The proposed system achieves reliable multiloop message relay across mesh nodes, maintaining communication where conventional systems fail, making it directly applicable to disaster response, remote area connectivity, and emergency coordination scenarios |
