What Is CSMA/CA? Definition from SearchNetworking

WebFeb 9, 2024 · CSMA/CA is a deterministic access method that controls use of the network. Explanation: Both CSMA/CD and CSMA/CA are contention-based access control methods. With CSMA/CD, each end device monitors the media for the presence of a data signal. If the media is free, the device transmits data. With CSMA/CA, each end device also examines … WebAlpha is a ratio of propagation delay over the frame transmission time. In one persistent CSMA, its maximum Throughput throughput is better than that of Aloha schemes for small alpha. But it is worse as alpha is greater than one. The other two CSMA options are non-persistent CSMA and p-persistent CSMA. Non-persistent CSMA is the least greedy.
