Comparative Study of Various Handover Scenarios in WiMAX Network

Today in wireless network field Worldwide Interoperability for Microwave Access or WiMAX (IEEE 802.16 standard) has emerged out as one of the most promising networking technologies. But in order to compete with the present existing other wireless technologies like Wi-Fi (IEEE 802.11), 3GPP/UMTS, Bluetooth (IEEE 802.15); WiMAX has to promise better QoS & cost efficiency. Along with the QoS today’s greatest network demand is mobility and mobility has to be supported by handover mechanism. So, this paper is focused upon the comparative study of various scenarios of handover technique in order to provide mobility to the WiMAX network along with enhanced QoS.
