SIMULATION OF WIDE AREA WIMAX NETWORKS IN URBAN AREAS

In recent years Wireless network plays an important role due to its flexibility and easy portability. WiMAX(World Wide Interoperability for Microwave Access) is the developing 4G promising network to cover the customer requirement. WiMAX is a technology that gives a connection between mobile and fixed networks and it handles wireless data for several distances from point to point links to all cellular type access. The coverage area of WiMAX is high when compared to other technology and it gives good support and stability. In this paper, simulation is conducted for a WiMAX network in the city of Mecca, Saudi Arabia. By considering the geographical area of the city, 10 base station nodes and several mobile nodes are assumed. Network simulator 3 (NS3)[ ]is employed to obtain parameters such as packet delivery ratio (PDR), delay, dropping ratio, throughput, and good put for two frequencies 2.4 GHz and 914 MHz[ 2
