In contention, any computer in the network can transmit data at any time (first come-first served). This system breaks down when two computers attempt to transmit at the same time.

It is worth noting that we propose particle access method and theory for (wireless) network by treating each packet as one “particle” [7]. For each “particle”, we utilize the
Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". When they do transmit, nodes transmit their … See more Collision avoidance is used to improve the performance of the CSMA method by attempting to divide the channel somewhat equally among all transmitting nodes within the collision domain. 1. Carrier … See more CSMA/CA can optionally be supplemented by the exchange of a Request to Send (RTS) packet sent by the sender S, and a Clear to Send (CTS) packet sent by the intended receiver … See more • GNET – an early proprietary LAN protocol • Apple's LocalTalk implemented CSMA/CA on an electrical bus using a three-byte jamming signal.
