Study on queue scheme of gated polling multi-access communication system

The gated polling multi-access communication system was analyzed in discrete time. By improving the queue scheme, the analytical expression of average queue length on the polling point and average message delay were obtained. The imbedded Markov chain theory and the generating function method were used. The simulation shows the analytical is reasonable and the performance is enhanced compared with ordinary polling gated system; With an simple and approximate arithmetic, the analytical expression of averagequeuelengthduringthepollingcycletimeispresentedandisinaccordancewiththeresultofcomputersimulation.
