WebThe Aloha protocol [4] is a fully decentralized medium access control protocol that does not perform carrier sensing. The subsequent slotted-Aloha protocol [5] was introduced to improve the utilization of the shared medium by synchronizing the transmission of devices within time-slots. WebThere are two basic types of ALOHA system, pure ALOHA and slotted ALOHA. In pure ALOHA a node can start transmission at any time. In slotted ALOHA, all nodes have synchronized clocks marking frame boundary times (the clock period is the time for one frame transmission) and a node wishing to transmit does so at the start of the next frame … WebAloha in computer networks is an access control protocol.
