Carrier sense multiple access/collision avoidance. CSMA/CA is a protocol that allows each node to sense whether or not a channel is in use before attempting to transmit information. CA is an algorithm by which channel time is reserved to avoid collisions.
(Carrier Sense Multiple Access/Collision Avoidance) - A method of data transfer that is used to prevent data loss in a network.
802.11 WLANs use CSMA/CA to minimize collisions by listening and waiting for a clear channel before transmitting. If the channel is not clear, devices wait for a random timer to expire before listening again. The timer will be reset as many times as necessary. Back
