Analisa Sistem Monitoring Greenhouse Berbasis Internet of Things (IoT) pada Jaringan 4G LTE

Abstract

A greenhouse monitoring system is a tool that works to monitor and observe conditions in the greenhouse both temperature, light intensity, air humidity and soil moisture. This monitoring system is connected wirelessly using Zigbee technology and connected to the open-source IoT (Internet of Things) application, namely Thingspeak using a cellular network. This research was conducted to test and analyze the performance of the IoT application when running on a mobile network to determine the effect of signal reception strength on delay, packet loss and throughput. Based on the test results, it was found that the network standard used only affects the number of TCP errors on 3G networks compared to 4G networks. But the network standard does not affect the performance of data transmission when viewed from the side of the delay, which is between 0.5 ms to 1.5 ms in both conditions. And then for the packet loss, which only occurs one time out of all six experiments conducted with the amount of packet loss only 2% and relatively the same throughput between 9.7 and 22 kbit / s. For the signal strength or the size of the RSRP (Reference Signal Received Power), the value does not affect the number of TCP errors, which are between 1 to 4 errors in all conditions and does not affect packet loss where packet loss does not occur in all test conditions. The RSRP value only affects delay and throughput and only in low conditions where at low signal conditions, there is an increase in delay from an average of 1 ms in high and moderate conditions to an average of 1.5 ms in low conditions, and throughput that is between 10 to 16 kbit / s in high and moderate conditions to 6 to 15.4 kbit / s in low conditions.
