Abstract

IEEE 802.16e standard known as Mobile WIMAX is found to enhance the weak of the IEEE 802.16 fixed-broadband access system. At the same time, IEEE 802.16m is the extension of IEEE 802.16e. Based on the literature review studies and remarks it can be concluded that in IEEE 802.16e and IEEE 802.16m the methodologies mostly focus on how to serve real time applications and give them higher priorities. This in fact is good, but most of them do not show the 1 required interest about the nodreal time applications. Non-real time applications still required extensive studied. In order to give non real time applications high priority as much as possible the technique known as minimum allocation is used, which means to allocate the required bandwidth for every service flow as its minimum demand. Unfortunately the challenge of minimum allocation is that if the bandwidth is more than services flow's requirements then the remaining bandwidth will be lost. The purpose of this research is to use all the allocated bandwidth where if all allocated band width is used correctly then the throughput of the system will be higher. In order to solve this challenge of minimum allocation an important technique is used which is round robin, it reallocate the unused bandwidth to all services flow with equal amount of the remaining bandwidth. In this research, real time applications are served with high quality of services, higher priority and non-real time applications is given a chance to reduce packets drop. These objectives are performed with a combination of two technologies which are minimum allocation and round robin technologies. Besides that, a comparison between IEEE 802.16e and IEEE 802.16m in terms of resource allocation, average delay, packet drop, and total throughput of the whole syste~nto show which one is affected by the algorithm more than the other is perform. In this case, the throughput of the total system is enhanced due to the reduction of noq-efficiency packets drop. In conclusion, the results of the simulations have proved that the packet drop will become equal to zero. Subsequently, the throughput per service and the total throughput of the system give higher level of the performance.
