Wide Area Network

Standar terbuka pada sistem komunikasi LoRa (Long Range) menyebabkan perbedaan cara implementasi dalam setiap penggunaannya. LoRaWAN (Long Range Wide Area Network) sebagai protokol bawaan LoRa masih mempunyai beberapa kekurangan yang menyebabkannya kurang efektif untuk diimplementasikan pada sistem tertentu. Penelitian ini mengembangkan protokol SLP (Simple LoRa Protocol) sebagai alternatif protokol komunikasi dan arsitektur jaringan yang didesain berdasarkan kekurangan yang dimiliki oleh LoRaWAN. Protokol ini mendefinisikan format data dan proses komunikasi antara client dan gateway dalam mode setup untuk pendaftaran node secara mandiri dan polling untuk transaksi data. Proses setup mampu mengenali node dengan konfigurasi sensor beragam dan dapat mengirmkan data dari node ke gateway dengan baik. Hasil pengujian menunjukkan bahwa SLP menghasilkan peningkatan performa QoS dalam throughput dan packet loss dari LoRaWAN menggunakan modulasi yang sama.

Low-power wide-area network (LPWAN) technologies are becoming a widespread solution for wireless deployments in many applications, such as smart cities or Industry 4.0. However, there are still challenges to be addressed, such as energy consumption and robustness. To characterize and optimize these types of networks, the authors have developed an optimized use of the adaptative data rate (ADR) mechanism for uplink, proposed its use also for downlink based on the simulator ns-3, and then defined an industrial scenario to test and validate the proposed solution in terms of packet loss and energy.

Long Range Wide Area Network (LoRaWAN) is the one of the promising low power wide area network (LPWAN) technologies at present and is expected to grow in the foreseeable future as a tool to provide connectivity among small things. In this paper, we present a simple analytical model to compute the throughput and packet loss probability of Medium Access Control (MAC) for Class-A of LoRaWAN. This analysis results can be used as a reference for deploying the appropriate number of end-devices (EDs) that can be accepted in a gateway (GW) while maximizing network throughput or guaranteeing the packet loss rate of EDs.
