Due to all potential options in BWA standards, at the
present time there is a significant interest by the research
community, manufactures and operators about what type of
performance can really be expected from IEEE 802.16-2004
[2] and IEEE 802.16e [3] certified equipment in the near
future. Recent studies found in the literature focus on system
performance regarding support of Quality of Service (QoS)
[4-7] and cross-layer issues [8-10] for the IEEE 802.16
MAC protocol. However, only relatively few studies [11-13]
explicitly approach the analysis of the Best Effort (BE)
service class in comparison to other service classes (UGS,
rtPS and nrtPS).
