Performance Evaluation of LoRaWAN for Smart Shuttle Bus System Support in Campus Area

Improving the accessibility of public transportation can be achieved by using a tracking system. However, some of the current tracking system technologies use a high operational cost and power consumption wireless connectivity. The use of a tracking system based on the Internet of Things (IoT) can address those problems. This study aims to evaluate the performance of Long-Range Wide Area Network (LoRaWAN) for smart transportation (shuttle bus) system support in campus areas. The performance evaluation uses six different configurations of date rate, DRO -DR5. The test was performed by placing the LoRaWAN based GPS tracker based on the shuttle bus roof and measuring several performance parameters, including Signal to Nosie Rasio (SNR), Received Signal Strength Indication (RSSI), and packet loss. The analysis of the test results is presented in comparisons of the performance parameters values and heatmaps based on the SNR and RSSI values on the shuttle bus route. The results analysis showed a slight difference value on SNR, RSSI and packet loss when using data rate DRO - DR5. Based on the performance evaluation, the LoRaWAN is able to provide reliable communication since the average SNR value is over 0dB, average value of RSSI is over −100dBm, and the maximum packet loss value is under 3% for each data rate.
