.~.~> Arbitration for access between contending stations {1}
DEFINITION
Classification: 370/445
Carrier sense multiple access (CSMA):
(under subclass 431) Subject matter having a reservation scheme for reaching a communication medium in which a station is assigned a carrier; the idle state of a communication channel is determined by sensing the presence or absence of a carrier signal on the channel.
(1) Note. CSMA with collision detection (CSMA/CD) or a listen while talk scheme (LWT) is the basis of the Ethernet protocol. In this scheme, a user listens to a channel while sending out a message and immediately ceases transmission before it is completed when a collision with another simultaneous transmitting user is detected.
