Medium Access Control Layer Design and Simulation for 802.16 System

Abstract:

In order to analyze transmission performance of broad band wireless communication system based on 802.16 protocol, address the key issues of QoS scheduling algorithm, and network congestion, etc, we present our design of WiMAX medium access control (MAC) layer based on 802.16 protocol in this paper. The implemented design comprises the service-specific convergence sub-layer (CS), the MAC common part sub-layer (CPS), a call admission control mechanism, and a scheduler. In the next simulation experiment, we tested the throughput and average delay of the system which we designed under the conditions in different time or number of clients. The design and simulation had provided a platform and foundation for further to improve the efficiency of bandwidth management algorithm, scheduling algorithm, QoS management, and enhancing the performance of WiMAX systems.
