WebSIMULATION AND COMPARISON OF PURE AND SLOTTED ALOHA. In this report we will present the comparison of Pure ALOHA and Slotted ALOHA protocols, through simulation results under different traffic loads. We will then compare the simulation results with theoretical results and analyze why they have different system performances. WebJun 23, 2024 · The maximum throughput of Slotted ALOHA is 1 / 0.368 e = , which occurs at 1 G = ; this is doubled of that of Pure ALOHA. As we can see, the efficiency of Pure ALOHA can be improved by the introduced time slot structure. However, time synchronization is required to align stations to the slot structure. matlab software free download latest version https://thomasenterprisese.com
