Abstract

This paper builds the Markov fluids analytical model in Relay System where bursty traffic packet arrival process is generated by Markov-modulated Poisson process and the transmission process is described by a phase-type process based on the channel state information.We obtain the system’s probability equilibrium equation and the asymptotic probability distribution of the system queue length using the master function method and get the method to achieve

.We use Maxtix-Geometric method to achieve the analytical expressions of effective capacity and the system’s equilibrium condition.Moreover

the other quality of service(QoS)performance metrics such as average queue length and packet loss rate are derived.The simulated result shows that the theory model and analysis are valid.
