WebDec 17, 2012 · Carrier Sense Multiple Access (CSMA) is a network protocol that listens to or senses network signals on the carrier/medium before transmitting any data. CSMA is implemented in Ethernet networks with more than one computer or network device attached to it. CSMA is part of the Media Access Control (MAC) protocol. WebCSMA/CA Carrier Sense Multiple Access with Collision Avoidance RTS/CTS Request to Send/Clear to Send How does CSMA/CA work System assembles a frame, asks if the channel is idle, if channel is idle transmit the data If channel is not idle wait a random time and ask if channel is idle again How does CSMA/CA with RTS/CTS work?
