Resumo

A crescente demanda por eficiência energética em ambientes urbanos, especialmente em cidades inteligentes, torna-se imperativa com a proliferação massiva de dispositivos IoTs nas redes 6G. Destacamos a relevância crítica da tecnologia LoRa para aplicações IoTs em ambientes urbanos, ressaltando a necessidade de otimizar parâmetros fundamentais, como o Fator de Espalhamento (SF) e a Potência de Transmissão (TP). O estudo compara nossa proposta de Programação Linear (PL) com métodos heurísticos e pseudoaleatórios, demonstrando que nossa abordagem se destaca notavelmente ao reduzir significativamente o consumo de energia durante as transmissões dos dados. Esses resultados indicam um potencial expressivo para aprimorar tanto o desempenho quanto a sustentabilidade de dispositivos IoT em redes 6G.
