Abstract
IEEE 802.16(d) i.e fixed WiMAX and IEEE 802.11 i.e Wi-Fi (wireless fidelity) have emerged as promising broadband access solutions for the latest generation of wireless MANs and LANs respectively. With the success of wireless technologies in consumer electronics, standard wireless technologies are deployed. Applications involving voice, video and data are supported both by wifi and wimax. Nonetheless these applications have different QoS requirements that need to be met. The main aim of this paper is to simulate an environment of Wi-Fi and Wimax network and investigate the comparative performance of individual environment with respect to QoS parameters like end-to-end delay, throughput and packet delivery ratio for 101, 151 and 201 number of nodes.
