The use of CSMA protocols has been proposed in heavy traffic conditions when ALOHA protocol starts to fail. Three network scenarios - Centralized, Distributed and Hybrid were envisioned in which p-CSMA and np-CSMA techniques were applied. Event-driven simulations were developed to analyze and compare their throughput and energy results. As LoRaWAN does not inherently possess carrier sensing, the CAD mode in LoRaWAN was studied and applied. This study provides insights into the implementation of unslotted carrier sensing techniques in LoRaWAN. It was concluded that, while the ALOHA like LoRaWAN can perform effectively under light load conditions, the throughput and probability of success of the CSMA protocols was better as the number of serviced devices per gateway increased. The average energy efficiency of the devices was observed to be better than the ALOHA in higher traffic loads.
