| Abstract | To observe the effects on the current best-effort service schemes and two extended differentiated service schemes while Poisson process is considered for the wireless data0/datal/data2 packet networks, the system performance models are developed and simulation model is prepared. The performance models are also considered for Pareto distributed service process. Pareto distribution is one of the typical distributions of the heavy tailed distribution. This research work represents the system performance models for calculating the blocking probability and mean delay of three incoming packets in wireless communications systems. This analysis and simulations are considered for both exponential and Pareto distribution service process. The obtained results are plotted as blocking probability and mean delay of packets verses all three types of packet arrival rates. The blocking probability and mean delay depend on the system characteristics, such as offered load, mean holding time, buffer size etc. In general, the arrival process of voice traffic follows Poisson process. So, in this research work, the same Poisson assumption is considered for wireless voice traffic model and the voice packet duration is assumed for exponential distribution. By comparing the results, it can be concluded that Premium service scheme shows the best performance among the above-mentioned three differentiated services considering both exponential and Pareto distributed service processes. It is found that the blocking probability and mean delay of voice packets are relatively less in Premium service scheme, which guarantees the quality of service of voice in the wireless communication network systems. Finally, among all differentiated service schemes, it can be concluded that Premium service is the best of the studied Internet service schemes |
