PERFORMANCE ANALYSIS OF AODV, DSDV AND AOMDV USING WIMAX IN NS-2

WiMAX (IEEE 802.16) technology empowers ubiquitous delivery of wireless broadband facility for fixed and mobile users. WiMAX standard describes numerous physical and MAC layer characteristics. Here, an attempt is made to implement some of these physical and MAC layer structures including the mobility extension 802.16e. NS2 (Network Simulator-2) is chosen as the simulator to implement these features as NS2 provides suitable library to simulate network scenario. The performance of the simulated module is analyzed by running AODV, DSDV and AOMDV routing protocols on a wired-cum-wireless WiMAX scenario. The throughput for each routing protocol is calculated for varying number of mobile nodes or subscriber stations.
Worldwide Inter operability for Microwave Access (WiMAX), is wireless broadband standard that has promised high bandwidth over long - range transmission. The standard identifies the air interface, including the medium access control (MAC) and physical (PHY) layers, of Broadband Wireless Access. WiMAX technology enables ubiquitous delivery of wireless broadband service for fixed and/or mobile users, and came into existence in 200 6 by Korea Telecom, when it started the deployment of a 2.3 GHz type of mobile WiMAX service called WiBRO in the Seoul metropolitan area to provide great performance for data and video.
