This research discusses the significance of monitoring toxic gases around volcanoes, with a focus on the implementation and evaluation of three communication protocol models in a Wireless Sensor Network (WSN). This research takes inspiration from the Sinila Crater tragedy in Dieng, Banjarnegara, Indonesia, which occurred in 1979, which involved poisonous CO2 gas from the volcano. The three models tested were Model-A (Pure-ALOHA), Model-B (Slotted-ALOHA), and Model-C (Modified Slotted-ALOHA). Model-C, which adopts the Master-Slave, Time Division Duplexing (TDD), and Two-Way Time Message Exchange (TTME) approach, is proven to have the highest data transmission success rate, reaching 100%, and good ability in avoiding data packet collisions. The Model-B, with Slotted-ALOHA and a timing system, also shows improved performance compared to the Model-A, which is similar to the Pure-ALOHA and does not have a timing system. The results of this study confirm that the Model-C is the best choice for monitoring toxic gases around volcanoes, which in turn can improve public and environmental safety. In particular, Model-C has been proven to be able to improve Quality of Service (QoS) in WSN networks, reducing data packet loss due to interference or collisions. © 2023 IEEE.
