The Overhead and Efficiency Analysis on WiMAX's MAC Management Message

This paper presents the overhead analysis on MAC Management Messages of WiMAX based on IEEE802.16 standard. The efficiency on the MAC layer is derived for Point to Multipoint (PMP) topology. The influence of several parameters is examined. The parameters, such as the number of subscriber stations in the network, various modulation and coding, and length of MAC message's PDUs, are assigned as the overhead parameters. The results show the specified parameters have significant impact on the efficiency of MAC layer. Finally, some recommendations to reduce the overhead are put forward.
