Viabilização de Alocação de Recursos em LoRaWAN
Keywords:
IoT, LoRaWAN, MILP, Resource AllocationAbstract
O LoRaWAN é uma tecnologia sem fio de longo alcance promissora em aplicações de Internet das Coisas (IoT). Esta tecnologia trabalha com alta densidade sendo capaz de conectar dispositivos que requerem comunicação de longo alcance, baixo custo e menor consumo de energia. Contudo, a densificação do uso de LoRaWAN em serviços IoT traz uma série de desafios devido a interferência por transmissão simultânea no mesmo canal. Nesse contexto, este artigo apresenta uma heurística e um modelo ótimo para alocação de recursos adaptativos no LoRaWAN para aplicações IoT. Os resultados obtidos por meio de simulações mostraram que a heurística CORRECT fornece resultados próximos ao ótimo obtido pelo modelo MARCO para uso do canal.
