Implementation and Performance Analysis of a WiMAX Module in ns-2

Abstract

WiMAX is a very promising wireless broadband technology. For all new technologies, performance studies are required and network
simulation is considered as a solution to test the performance of any upcoming technology. In ns-2 (a very popular and open source network
simulator), may protocol modules (like 802.3, 802.11, 802.15 ) have been implemented, but the IEEE-802.16 (WiMAX) module have not
been incorporated yet (till version ns-2.32). In this paper, a WiMAX module for the ns-2 simulator (v 2.32) has been implemented. This
module is based on the analysis presented by Chen et.al,2006. Some simulation scenarios are also been analyzed to test the module and the
same simulations are also been done on NCTUns-4.0 that has an implemented 802.16d module.
