Queueing analysis on a CSMA/CD packet switched mobile network with capture

The capture effect on a CSMA/CD protocol for a mobile radio-telephone network, without hidden users and fading effects is analysed and discussed. Various system parameters, like packet length, time recovering from collisions resulting in no successful transmission, attempt rate and the signal-to-noise ratio are studied in detail. A Markov model is constructed based on the regenerated time instants between successful transmissions, and the slot property of the channel. It is shown that such a system exhibits stable operation, and that for moderate values of the system parameters a considerably better performance in the throughput delay trade off than the conventional δ-CSMA/CD schemes can be achieved
