CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is a media access control (MAC) protocol used in wireless local area networks (WLANs), such as those based on IEEE 802.11 standards. In CSMA/CA, a station will sense when the channel is idle and can then start transmitting a frame. If two stations attempt to transmit at the same time, they will both become aware of the collision and each one will stop sending and wait for a random period before attempting to retransmit. This ensures that the channel can be utilized more efficiently, since less time is wasted in resolving collisions.
