| Abstract: | A policy of parallel schedule is proposed for a polling system with limited service (K = 1) in continuous time.The system enables simultaneous polling and transmissions of information packets.By the imbedded Markov chain theory and the generating function method,the mean values of queue length and information packet waiting time are explicitly obtained.The stabilities of polling systems are analyzed.Mathematical analysis and simulation results show that the parallel schedules are more efficient. |
