IEEE 802.16 E&M SYSTEMS BANDWIDTH RESOURCE ALLOCATION PERFORMANCE INVESTIGATION

This paper concentrates on the downlink resource allocation strategyfor the bandwidth in Mobile WiMAXsystem based on IEEE802.16E and IEEE802.16M standards. Most of the recentalgorithms dealwith giving higher priority to the applications that have higher delay tolerance known as real-timeapplications. While the applications using the non-real time doesn’t have enough priority or interest. still,the real-timeapplications should have a higher priority than the non-real time applications to be servedfirst. In this paper, a higher priority and QoS (quality of services) will be given to the real-timeapplications while the applications for the non-real time will be helped to give some fairnessto decrease the dropping packets withoutstarving. It will be done by merging two major technologies (minimum resource allocation and round robin manner. Also, a comparison will be done between the IEEE802.16E and IEEE802.16M systems to evaluate thesystem throughput, the resourceallocation, the average end-to-end delay, and the data packet dropping to demonstrate the affecting algorithm of the entire system. Finally,the paper will demonstrate that the total system will be enhanced by reducing the nonefficientdropping packets. As a result,it will simulate and verify that there is lesser packet drop in the applications of real and non-real time. therefore,everysingle service and the total system throughput will be enhanced.
