Abstract

This research presents the design and experimental evaluation of LoRa-based vehicle-to-vehicle (V2V) communication system that can be used to transmit real-time hazard notifications without any dependence on cellular networks or roadside infrastructures. The design uses the ESP32 microcontroller with LoRa modules built using the SX1278 transceiver for the implementation of a peer-to-peer communication system in automobiles. The communication procedure includes hazard detection, packet creation, wireless transmission, and alerting components. The experimental analysis of the system was conducted by manipulating the environmental parameters like LOS (line-of-sight) and NLOS (non-line-of-sight). Evaluation performance measures include packet delivery ratio (PDR), received signal strength indicator (RSSI), latency, and communication distance. The experiment results demonstrate successful communication at a distance of 600 meters in LOS conditions, with a PDR of greater than 95% and latency lower than 250 ms.
