Abstract
One of the most aims of IEEE 802.16 (WiMAX) is to present high speed wireless access to cover wide range coverage. The base station (BS) and the subscriber station (SS) are the main parts of WiMAX. WiMAX uses either Point-to-Multipoint (PMP) or mesh topologies. In the PMP mode, the SSs connect to the BS to gain access to the network. However, in the mesh mode, the SSs connect to each other to gain access to the BS. There are several coding and modulation schemes using in WiMAX, such as QPSK and QAM. We use QualNet 5.0.2 to study the performance of different coding and modulation schemes when the numbers of SSs or MSs in station or mobile WiMAX environments increase. We find that when the number of SSs increases, the average jitter and average end-to-end delay is increased and the throughput is reduced.
