WebMar 29, 2024 · Pure ALOHA is a simple protocol allowing multiple nodes to share a single communication channel. However, it is inefficient due to the high probability of collisions. Thus, it laid the foundation for developing more sophisticated random access protocols, such as Slotted ALOHA and CSMA/CD. WebThe throughput of the protocol is 0.75*10 = 7.5 Megabits/s. The packet collision rate is therefore equal to . 1–7.5/8 = 1/16 = 6.25%. Problem 10.
