Performance Analysis of Integrated Voice and Data Systems Considering Different Service Distributions

In this study, the aim was to evaluate the effect of service distributions on system performance for the proposed voice and data model. For this purpose, the integrated voice and data system with a single buffer and a channel was considered and analysed using discrete event simulation. Mainly, four different distributions; exponential, normal, lognormal and weibull distributions were taken into account for service time, while packet arrivals followed a Poisson process. Simulation results revealed that service distribution has a great effect on system performance and weibull distribution fits well for the proposed model.
