| dc.description.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. | en_US |
