The Network Simulator 2 (NS-2) is a popular discrete event simulator target at networking research. This tool can suport simulation of TCP, routing, and MAC protocols over wired and wireless networks. Although it's possible to simulate wireless local area network (IEEE 802.11), ad hoc networks and satellites networks, ns does not provide a WiMAX module. This project implements a WiMAX module based on the IEEE 802.16 standard for the ns-2 simulator, release 2.28. The focus of this implementation is the MAC layer and its mechanisms for bandwidth allocation and QoS support. The module implements the 802.16 five service flow types and their bandwidth request/grant mechanisms; moreover, it allows users to configure the QoS requirements of applications. Service flows are modeled by finite sate machines that capture how each service type react to different events. This module supports TDD mode and PMP topology. The wireless channel available in the ns-2 simulator is used. The module design was based on a module (http://portal.acm.org/citation.cfm?id=1273047) designed to simulate the DOCSIS standard. Although code reuse was possible, several modifications in the DOCSIS module code were necessary to make it compliant to the IEEE 802.16 standard.
