Performance of collaborative codes in CSMA/CD environment

Abstract

AbstractA new medium access control scheme is proposed for implementing collaborative codes in a system using carrier sense multiple access with collision detection protocol (CC‐CSMA/CD). We also propose a new backoff algorithm which is simple to implement and to analyse. A discrete‐time Markov chain analytical model is developed for CC‐CSMA/CD. The resulting model describes the regular CSMA/CD as a special case. Protocol performance measures were studied such as throughput, packet acceptance probability, average packet delay and channel utilisation. It is found that CC‐CSMA/CD offers improvements over a system that uses CSMA/CD in terms of throughput, packet acceptance probability, delay and channel utilisation. Copyright © 2006 AEIT.
