Abstract

The massive number of Internet of Things (IoT) applications is allowed by Low-Power Wide-Area Networks (LPWAN) with an extensive geographical area, low bit rate, and longevity specifications. The LoRa technology is a notable LPWAN that utilizes a proprietary Chirp Spread Spectrum (CSS) physical layer. Simultaneously, the LoRaWAN is defined as the media access control (MAC) protocol for large-scale deployment. It is intended to let low-powered applications to interact with massive requests that are connected through extensive wireless links. The aimed dense network distribution will inescapably lead to a scarcity of radio resources and have an issue with scalability when massive devices are connected to the network. In this paper, we propose a mathematical model to improve the link budget and scalability of LoRaWAN networks. Simulations using Matlab for different network scenarios illustrate the effectiveness of the optimization procedure.
