IEEE802.16 MAC Management Messages: The overhead and efficiency analysis in mesh topology

摘要

This paper presents the analysis of MAC Layer (L2) in wireless broadband system based on WiMAX IEEE802.16. The analysis is focused on overhead and efficiency of MAC Management Message and derived for mesh topology. The Mesh topology is evaluated concerning both existing types of scheduling-centralized and distributed-and their performance is compared. Some parameters, which deduced to have considerable influences i.e. the number of subscriber stations in the network, number of hops, various modulation and coding, and length of MAC PDUs, are assigned as the overhead parameters. The results show those parameters have significant impact on the efficiency of MAC layer.
