Diminution of contention period of Carrier-sense multiple access with collision detection (CSMA/CD)

Abstract

Carrier- sense multiple access with collision detection (CSMA/CD) is a media access control method used most notably in early Ethernet technology for local area networking. It uses a carrier -sensing scheme in which a transmitting station detects collisions by sensing transmissions from other stations while transmitting a frame. When this collision condition is detected, the station stops transmitting that frame, transmits a jam signal, and then waits for a maximum time interval before trying to resend the frame. Our aim to reduce the propagation time less than 2Ƭ.In this thesis try to every node or transmitter can not wait 2Ƭ and every node or transmitter there have own sequence time to transmit.
