Abstract

On this research, Internet of Things (IoT) as an advanced technology is used to monitor the height of trash from a trash can in order to give notification whether the height of trash is already reaching the maximum height limit or not. To support those needs, we used NodeMCU as a microcontroller, ultrasonic sensor, MQTT as IoT protocol, and Android to display the data. After we did the system performance test, we had the biggest result of end-to-end delay which was 2.06875 seconds when the packet delivery was set to 1000 ms with 3 active nodes and the smallest result of end-to-end delay which was 0.26055 seconds when the packet delivery was set to 100 ms with 1 active node. The biggest result of throughput was 597.17 Bytes/s when the packet delivery was set to 100 ms with 1 active node and the smallest result of throughput was 75.86 Bytes/s when the packet delivery was set to 1000 ms with 3 active nodes. The biggest result of availability and reliability was 99.905% when the packet delivery was set to 1000 ms and the smallest result was 99.833% when the packet delivery was set to 100 ms.

Abstract

The Aquaponic is a farming system which need attention because their system will mutually influence each other. Then using IoT technologies, can be made aquaponic that can automatically control and monitoring the aquaponic. The prototype using nodeMCU as a microcontroller, and for communication the system using MQTT protocol and android application as a user interface. The purpose of this research is to provide convenience for aquaponic user to be able to control remotely. In addition, this research aim is to analysis the QoS performance of the prototype. This research uses 2 scenario testing, there is with changing the distance between sensor nodes and access point, and testing the system in a normal state. Based on the results of the testing that has been done, the farther the distance range of the sensors node with access point then declining system performance. But in the normal state test, the median value of the mean delay was 0.10512s and the median value average throughput was 566 Bytes/s. In addition the median value also obtained the mean availability and realibility system that is 98.258% and 98.204%. Refers to the standard TIPHON (DTR/TIPHON-05001), the QoS performance of this system include excellent category.

Abstract

IEEE 802.11 standard is a WLAN (Wireless LAN) standard that has been used in all over the world. IEEE 802.11ah is the newer technology that designed to supports Internet of Things (IoT) and Machine-to-machine Communication (M2M). IEEE 802.11ah has a feature called Restricted Access Window (RAW) that capable to reduce power usage and have satisfying Quality of Service (QoS). In this research, Enhanced Distributed Channel Access (EDCA) is also applied. Same as RAW, EDCA also be able to affect QoS by modified the MAC Layer in 802.11 standard. This research used 3 different scenarios for RAW parameters: Modifying the number of RAW Group, Modifying the number of RAW Slot, and Comparing 2 Datamode. The EDCA Parameters that used in this research were: Contention Window and Arbitrary inter-frame Spacing Number. The values that expected to be the output in this research are: Delay, Throughput, Packet Delivery Ratio, Availability, and Reliability. After the research has been simulated, the results are: First, the lowest of average delay was Ngroup = 1, the highest of PDR was Ngroup = Nsta/2, and the highest of Throughput was Ngroup = Nsta/2. Second, the lowest of average delay was RAW Slot = 6, the highest of PDR were RAW Slot = 3 and 4, and the highest of Throughput was RAW Slot = 4. Third, the lowest of average delay was Datamode 3,9 Mbps BW 2 MHz, the highest of PDR was Dat mode 3,9 Mbps BW 2 MHz, and the highest of Throughput was Datamode 3,9 Mbps BW 2 MHz. Reliability, Availability, and Energy Consumption also can be affected by modifying RAW parameters, in 802.11ah Energy Consumption can be reduced by increasing the number of RAW Stations and RAW Groups.
