Abstract
WiMAX is a very promising technology. The main promises are the high throughput and the large coverage. As for all new technologies, performance studies are required. The network simulation is considered as a solution to test the performance of technologies and especially the wireless networks. In this paper, we propose a new WiMAX module for NS-2 simulator. This module is based on the NIST implementation of WiMAX [5]. Our contribution consists of the addition of the QoS classes as well as the management of the QoS requirements, unicast and contention request opportunities mechanisms, and scheduling algorithms for the UGS, rtPS and BE QoS classes. Simulation results provide interesting observations about the throughput and mean sojourn time values. Simulation results show that our UGS, rtPS, and BE schedulers are in accordance with the specification of the QoS classes defined in the IEEE 802.16 standard.
