SIMULATION BASED ANALYSIS OF IEEE 802.16 WIMAX ROUTING PROTOCOLS FOR HIGH LOAD APPLICATIONS

ABSTRACT Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Routing is the key issue of WiMAX. Routing protocols are studied mainly on the basis of distance vector routing protocols, link state routing protocols and path vector routing protocols and the protocols are IGRP, RIP, EIGRP; OSPF, IS-IS and BGP respectively. The performance of each routing protocols is different from others. Optimized Network Engineering Tool (OPNET) simulator is used to analyze and measure the comparative performance of various routing protocols. In this paper, focus is made on comparative analysis of routing protocols for high load application such as FTP. The performance evaluation of three routing protocols that are Border Gateway Routing (BGP), Open Shortest Path First (OSPF) and Interior Gateway Routing Protocol (IGRP), is carried on the basis of End to End delay, network load, Media Access Delay, Retransmission Attempts and Throughput. The analysis is done by obtaining the results from simulation scenarios in OPNET Modeler version 14.0.
