Executive Summary

The IEEE 802.16 standard does not define or recommend any algorithm for measuring whether a flow exceeds its maximum sustained traffic rate. However, in this standard the Service Data Units deemed to exceed the granted bandwidth may be delayed or dropped. In addition, nodes would behave maliciously by requesting more resources than their requirements just to deny other nodes from having access to the network. In this paper, the authors propose a Policy-Based Trust-Aware Adaptive Monitoring Scheme that can be integrated with the basic architecture of WiMax network to enhance its overall quality of service.
