IMPLEMENTATION IMPLEMENTATION OF DATA TRANSMISSION WITH LONG RANGE COMMUNICATION MODULE (LORA) AND MQTT-SN PROTOCOL TO SUPPORT SOIL HUMIDITY SENSOR DATA TRANSMISSION
Abstract
Wireless sensor network can help remote data transfer. Implementation of wireless
sensor network in IoT system must be done with a good planning because IoT system typically
have limited system resources. This limitation can affect performance of a wireless network
sensor. The purpose of this study is to find out the effect of node range to the data transfer
performance in terms of delay, throughput, RSSI, and SNR by using QOS (quality of service)
analysis for LoRa and MQTT protocol. The results of LoRa’s protocol delay are between 2,82
ms to 37,27 ms. Throughput between 0,61 Kb/s to 24,29 Kb/s. SNR between 2,7 dBm to 8,34
dBm, and RSSI between -74,92 dBm to -122,36 dBm. On the other hand, the results of MQTT’s
protocol delay are between 677,49 ms to 1182,69 ms. Throughput between 0,60 Kb/s to 1,12
Kb/s. SNR between 2,7 dBm to 8,34 dBm and RSSI between -74,92 dBm to -122,36 dBm.
