Performance Analysis of Reactive and Proactive Routing Protocols under Varying Mobility in WIMAX Environment

Abstract: Worldwide Interoperability for Microwave Access (WiMAX) is currently one of the hottest technologies in wireless, it‟s a standard-based on the IEEE 802.16 wireless technology that provides high throughput broadband connections over long distance, which supports Point to Multi-point (PMP) broadband wireless access. This paper presented an analysis on those routing protocols especially designed for wireless networks. A study and comparison on the performance of reactive protocol (AODV) and proactive protocols (OLSR , DSDV) for Mobile WiMAX environment is done under varying mobility conditions. The performance matrix includes Packet Delivery fraction (PDF), Throughput, End to End Delay, and routing load were identified. The study used NS2 simulator for the comparison on the performance analysis. Successfully results found that AODV protocol outperforms OLSR and DSDV routing protocols.
