Executive Summary

IEEE 802.16 telecommunication protocol defined by the respective networking standard specifies a high data rate wireless broadband network with inherent support for various multimedia applications. Media Access Control (MAC) layer of IEEE 802.16 provides unified service for the set of physical (PHY) layer profiles, each of which corresponds to a specific operation environment. Currently, the authors observe the proliferation of IEEE 802.16-based networks due to their relatively low cost, wide coverage and MAC mechanisms supporting a variety of Quality of Service (QoS) requirements. Performance evaluation of IEEE 802.16 QoS mechanisms is addressed by numerous research papers. In particular, the so-called bandwidth reservation stage is often considered, at which a network user can reserve a portion of the channel resources.
