πProject Overview
This project aims to develop an innovative mesh network-based chatting system that leverages Wi-Fi Direct technology to establish direct communication links between devices without requiring a central server or internet connection. The system will enable users to send and receive messages via a peer-to-peer (P2P) mesh network, where each device operates simultaneously as both a router and an end device.
The Wi-Fi Direct-based network will significantly extend the communication range and data transfer capabilities compared to traditional Bluetooth-based systems. The project will be implemented using two cutting-edge technologies: React Native for cross-platform mobile development and Flutter for creating a beautiful, performant, and unified user experience. Both versions will incorporate Wi-Fi Direct for device communication and end-to-end encryption for enhanced security.
