“…This affects the state of the signal resulting in an attenuation signal [17], [22]. Therefore, the function of the Additional AP is to strengthen signal reception in receivers or EDs and reduce packet loss or increase throughput [20]. Figure 2 is an example of ADR representation to make it easier to understand Adaptive Data Rate Mechanism on Multi Wall.…”

A new approach has been developed to provide an overview about signal behavior in indoor environments using Cost-231 Multiwall Model (Cost-231 MWM) and Adaptive Data Rate (ADR) method. This approach used as a reference for access point (AP) placement for campus building. The Cost-231 MWM plays a role in estimating the measured power received by user (usually called as Received Signal Strength Indicator/RSSI) by considering the existence of obstacles around the transmitter (AP). We used Institut Asia Malang environments as the case study and gave some recommendations for AP placement: ten optimal placements for the first, third and fourth floor, also seven optimal placements for the second floor. These recommendations were based on the RSSI for good and excellent level signal (-50 dBm until -10dBm). This research also uses the Adaptive Data Rate (ADR) mechanism approach to reduce the amount of packet loss (kbps) resulting from obstacles that cause attenuation (-dB). With the Adaptive Data Rate mechanism, it means increasing the number of access points, the signal attenuation (-dB) occurs from the obstacles (Walls) that are penetrated by the Radio Frequency device and causes attenuation (-dB), the more Access points on the Multi-Wall, will allow communication and data transmitting stability.

“…The last thing is about ADR Response, if successful then ADR Success, and go to the un-schedule ADR process. The ADR algorithm is often used for Low Data Rate data such as that of LoRa and together with Spreading Factor analysis (6-12) [15],] [20], [23].…”

“…are three classifications in the RSSI Analysis, i.e., Free Space, Building, and Hill and Tree Obstacles. The development of data analysis is at the level of comparison of Spreading Factor [16], [18], Bandwidth, Time on Air, and other analyzers on LoRa and LoRaWAN.…”

This study discusses the Performance of Moisture soil sensor, which is useful as a sensor to detect soil moisture level used as plant nutrition. The monitoring process is carried out in real-time using internet of things technology based on LoRa or Long-Range Radio Frequency (IoT-LoRa). The application server used is Thingspeak. With this research, agricultural processes and monitoring can be carried out dynamically and efficiently. Therefore, when the soil conditions are dry or the soil moisture level is <300, it will immediately affect automatic watering by opening the valve or rotating the Servo motor. Furthermore, the watering process can be done automatically by looking at the soil conditions on potted plants or agricultural land. The position of the sensor on the ground level is not immediately removed and moved to another place, but it is always in the same condition and location, so the Adaptive Data Rate mechanism is used for the management of Power Consumption on IoT-LoRa
