Performance and analysis of resource allocation in IEEE802.16E and IEEE802.16M Wimax model systems
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...

| தொகà¯à®ªà¯à®ªà¯: | 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. |
