Mesh-based LoRa communication has emerged as a practical solution for extending connectivity in environments where single-hop transmission is limited by distance, obstructions, or the absence of centralized infrastructure. This work investigates the performance of a self-operated LoRa mesh network based on the Meshtastic protocol, targeting linear urban infrastructures where centralized network operators and multiple gateways are unavailable. A custom simulation framework is developed to model multi-hop communication using fixed node placements along the Széchenyi Chain Bridge, Margaret Bridge, and Liberty Bridge in Budapest, enabling realistic evaluation of routing behavior and hop formation. Network performance is assessed in terms of packet delivery ratio (PDR), end-to-end latency, hop count, and energy consumption under varying traffic and hop-distance conditions. The results show that the Meshtastic-based multi-hop forwarding protocol achieves high delivery reliability across extended paths, while latency and energy consumption increase predictably with hop count and traffic load. Despite these overheads, the observed performance remains suitable for delay-tolerant IoT monitoring applications deployed in constrained or infrastructure limited environments. The findings provide insight into the operational characteristics of the Meshtastic LoRa mesh protocol and support its applicability for robust, low-power IoT deployments without reliance on centralized gateways.
