“…Salah satu protokol komunikasi yang dapat diimplementasikan dalam WSN adalah protokol LoRa. Protokol LoRa memiliki cakupan jarak yang luas dan kemampuan penetrasi sinyal yang baik, sehingga sangat cocok digunakan untuk daerahdaerah yang sulit dijangkau oleh jaringan seluler [12][13][14] [15]. Dengan memanfaatkan teknologi LoRa, setiap Sensor Node dapat mengirimkan data dengan andal ke Sink Node, bahkan jika berada di wilayah blank spot.…”

tanah longsor yang tinggi, dipengaruhi oleh topografi yang bervariasi. Studi ini mengevaluasi potensi bencana tanah longsor dan upaya mitigasi di wilayah ini. Data dari Badan Pusat Statistik (BPS) mencatat jumlah kejadian tanah longsor, dan Pemerintah Jawa Timur telah membentuk Badan Penanggulangan Bencana Daerah (BPBD) untuk manajemen risiko. Tim peneliti dari Institut Teknologi Nasional Malang mengembangkan Landslide Monitor (LSdM), sebuah Wireless Sensor Network (WSN) menggunakan teknologi Long Range (LoRa). Fokus utama adalah pada Quality of Service (QoS) jaringan LoRa. Hasil pengujian menunjukkan kemampuan LSdM dalam kondisi Line of Sight (LoS) dan Non Line of Sight (NLoS), dengan analisis frekuensi LoRa menyoroti perbedaan dalam tingkat kehilangan paket. LSdM diharapkan dapat meningkatkan manajemen risiko bencana tanah longsor di Malang Raya.

Real-time monitoring is essential for solar-powered systems as they can be affected by sudden environmental changes, which may occur unpredictably, especially in isolated regions. This study proposes a wireless communication-based approach that allows for data acquisition and system monitoring of the entire solar system of a remote oil well. The proposed instrumentation method offers an affordable solution for monitoring the battery voltage, photovoltaic (PV) current, the converter's alternating current (AC), and oil well management. A wireless communication tool for a long-range called LoRa is used, with the TTGO LoRa32 SX1276 organic light-emitting diode (OLED) as the sender node and Heltec long range (LoRa) ESP 32 as the transmitter node. These I.C.s are ESP32 development boards with an integrated LoRa chip and an SSD1306 flash memory. System design and some test results are included in the paper.

“…Although there are LoRa network projects and technologies with real implementations presented such do not provide details about the actual environment. There are many studies on communication distances and future collisions, but few studies on problems in the real environment [16]. From these studies, it has been shown that the actual performance of LoRa falls with respect to smart farms.…”

In our modern world, many Internet of Things (IoT) technologies are being researched and developed. IoT devices are currently being used in many fields. IoT devices use Wi-Fi and Bluetooth, however, communication distance is short and battery consumption is high. In areas such as smart cities and smart farms, IoT technology is needed to support a wide coverage with low power consumption. Low Power Wide Area (LPWA), which is a transmission used in IoT supporting a wide area with low power consumption, has evolved. LPWA includes Long Range (LoRa), Narrowband (NB-IoT), and Sigfox. LoRa offers many benefits as it communicates the longest distances, is cheap and consumes less battery. LoRa is used in many countries and covers a range of hundreds of square kilometers (km2) with a single gateway. However, if there are many obstacles to smart cities and smart farms, it causes communication problems. This paper proposes two (2) solutions to this problem: the relay method which is a multi-hop method and the Automatic Repeat Request (ARQ) system that detects packet loss in real-time and requests retransmission for LoRa. In this study, the actual performance of LoRa in the problematic environment was measured and the proposed method was applied. It was confirmed that the transmission rate of LoRa dropped when there were many obstacles such as trees. To use LoRa in a smart farm with a lot of space, multi-hop was observed to be better. An ARQ system is needed to compensate for the unexpected drop in the forward rate due to the increase in IoT devices. This research focused on reliability, however, additional network methods and automatic repeat request (ARQ) systems considering battery time should be researched in symmetry. This study covers the interdisciplinary field of computer science and wireless low power communication engineering. We have analyzed the LoRa/LoRaWAN technology in an experimental approach, which has been somewhat less studied than cellular network or WiFi technology. In addition, we presented and improved the performance evaluation results in consideration of various local and climatic environments.
