A comprehensive study and performance based evaluation on routing protocols of WiMAX

Worldwide Interoperability for Microwave Access (WiMAX) technology is a subdivision of the vast field of wireless communications, which breaks the restrictions of DSL, cable-modem or T1 infrastructure based wire line of our broadband Internet connections [1]. Wireless networking has become an important area of research in academic and industry. The four high-speed intensive applications such as high-speed data, video, voice and streaming media are being served properly by the WiMAX network, which overcomes the term digital divide. It has a number of spearhead applications with at-home and dynamic internet accessibility along with large geographical coverage and relatively low expense to pursuit. Routing overhead, unidirectional link support, delay, throughput, QoS support and multicast are the analysable terms by whom we can define the WiMAX protocols. To attain best use of this technology selection of suitable protocol is very important. In our paper, most imperative protocols of 802.16 WiMAX network called AODV, DSDV and OLSR is ventilated as well as further criticized in accordance with their performance on WiMAX where AODV is a reactive (on demand) protocol and both DSDV and OLSR are proactive.
