A WiMAX segmentation for 3rd generation N/W simulator

NfW Simulater-3(ns-3) is a next generation for modeling and simulation planed as a substitute of the network simulator-2 (ns-2). It enables sufficient firm of features and is designed for the basic need of the technical and scientific community, ns-3 is in its running process and work at different version which is still ongoing. With the recent emergence of wireless networks, simulation and modeling support for such networks, especially WiMAX segmentation, is becoming a basic requirement. In this paper, we propose and discuss in detail the design and implementation of a WiMAX segmentation for ns-3, with the Point-to-Multipoint (PMP) mode and the Wireless MAN-OFDMPHY layer. Our segment implements fundamental functions of the convergence sublayer (CS) and the MAC sublayer, including quality of service (QoS), band-width request mechanism, and a simple uplink scheduler. Our aim is to provide a standard partition in ns-3 with object-oriented WiMAX segmentation and well designed implementation of the standard. General Terms Segment, Design, Process, Techniques.
