WebCSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is a protocol for carrier transmission in 802.11 networks. Unlike CSMA/CD (Carrier Sense Multiple Access/Collision Detect) which deals with transmissions after a collision has occurred, CSMA/CA acts to prevent collisions before they happen. WebBy Dinesh Thakur. ALOHA: ALOHA is a system for coordinating and arbitrating access to a shared communication Networks channel. It was developed in the 1970s by Norman Abramson and his colleagues at the …

WebCSMA/CA. ALOHA. The earliest method used for random access was ALOHA and it was developed at the University of Hawaii in early 1970.ALOHA was mainly designed for radio/Wireless LAN but it can also be used for shared mediums. As the medium is shared between the stations, when a station sends the data then the other station may attempt … WebOther technologies, including CSMA/CD protocol, were also developed with the help of this process, which later became known as IEEE 802.3. This process also led to creating a token bus (802.4) and token ring (802.5). In 1983, the IEEE technology became standard, and before 802.11, 802.3 was born.
