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. Webnon-persistent CSMA Give up, or send after some random delay Problem: may incur larger delay when channel is idle 1-persistent CSMA Send as soon as channel is idle Problem: blocked senders all try to send at once P-persistent CSMA If idle, send packet with probability p; repeat Make sure (p * n) < 1

WebCSMA/CA is derived from CSMA/CD (Collision Detection), which is the base of Ethernet. The main difference is the collision avoidance: on a wire, the transceiver has the ability to listen while transmitting and so to detect collisions (with a wire all transmissions have approximately the same strength). ...

"Web0. I don´t think it is possible. CSMA/CA is used where the medium is common to all the devices in tx and rx (like Wifi), that´s why it is half duplex and need to avoid collisions. In the beginning there was a ring network using a coaxial cable and "T" connectors, so collision avoidance and half duplex made sense. " - Csma/ca and csma/cd protocol ppt
