IEEE 802.16 E&M Systems Bandwidth Resource Allocation Performance Investigation

This paper concentrates on the downlink resource allocation strategy for the bandwidth in the Mobile WiMAX system based on IEEE802.16E and IEEE802.16M standards. Most of the recent algorithms deal with giving higher priority to the applications that have higher delay tolerance known as real-time applications. While the applications using the non-real-time don’t have enough priority or interest. still, the real-time applications should have a higher priority than the non-real-time applications to be served first. In this paper, a higher priority and QoS (quality of services) will be given to the real-time applications while the applications for the non-real-time will be helped to give some fairness to decrease the dropping packets without starving. 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 the system throughput, the resource allocation, 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 nonefficient dropping packets. As a result, it will stimulate and verify that there is lesser packet drop in the applications of real and non-real-time. therefore, every single service and the total system throughput will be enhanced.
