Abstract

Designing a reliable telecommunication network for Advanced Metering Infrastructure (AMI) is crucial. This paper focuses on using LoRaWAN as the network and improving transmission reliability while maintaining fairness among smart meters. The Spreading Factor (SF) of LoRaWAN is used to control Packet Delivery Ratio (PDR) and measure reliability. Higher SFs increase redundancy and reliability, but collisions can occur between meters with the same SF. To optimize SF assignment, an SF assignment problem is solved to maximize the minimum achievable PDR, ensuring fairness. A novel solution called Reliable SF Assignment (RSFA) using a game of learning automata is proposed. Simulation results demonstrate that RSFA outperforms four conventional SF assignment approaches (ADR, AD MAIORA, CA-ADR, and EWS). RSFA improves packet collision rate, PDR, the number of served meters, and fairness index, albeit with a slight increase in transmission delay.
