Offline Mesh Messaging Engineered for Community Resilience
ResQMesh leverages **LoRa (Long Range)** radio frequency modules that operate at sub-gigahertz ISM bands. Unlike conventional radios, LoRa utilizes chirp spread spectrum (CSS) modulation, which allows transmission of packets over several kilometers under thick canopy, buildings, or heavy weather, all while using minimal power.
In a disaster event, individual ResQMesh nodes form a **dynamic, peer-to-peer mesh network**. If Node A cannot reach the main command gateway directly, Node B and Node C automatically act as relays (hops), forwarding the SOS telemetry. This ensures coverage extends organically as more devices join the mesh.
Hover over nodes to see connections in the self-healing mesh layout.
Developed as an academic capstone, ResQMesh intends to lower the barriers to entry for disaster communications.
Targeted testing across the urban center (Poblacion) and surrounding agricultural barangays susceptible to landslides and typhoons.
Utilizing ESP32 microcontrollers combined with SX1276 LoRa transceivers for inexpensive, community-built deployment kits.
Connecting verified households to civic responders directly during power outages to facilitate medical emergency dispatches.
