Abstract:

In recent era, ubiquitous, high Quality of Service (QoS), pledged mobile data is exceedingly demanded. With the mass enhancement of research activities QoS guarantee mechanisms are becoming significant. IEEE 802.16 promises to provide wireless access over long remoteness in a variety of momentums and becoming challenging in wireless environments. We have analyzed and focused different QoS parameters on various scheduling services observed in our simulated WiMAX network. The simulation study considers throughput, packet delivery ratio, number of packets dropped, delay and jitter parameters with three core services for handling essential traffic of ERTPS, RTPS and UGS . We have considered various packet sizes analyzed with each of the service separately. The study also considered the data rate change effects amongst these service parameters. On the basis of our simulations we propose to use the packet size of 200 to ensure the delivery of maximum packets to the destination. We suggest the fewer throughputs of dropped packets in order to improve the QOS. Comparative performance of UGS and RTPS are also studied. The highest priority of UGS is investigated amongst all the studied services. These investigation studies and achievements have never been reported in the literature till date to the best of our knowledge. We address the trade-off problem of longer delay and packet drops in ERTPS connection during contention period in the current study and propose a new strategy for admission control design at BS for its resolution as a future study.
