چکیده
WiMAX is a broadband wireless access (BWA) scheme based on IEEE 802.16. This is an emerging technology that aims at providing last mile access internet and data services. Since 2001, WiMAX has evolved from 802.16 to 802.16d standard for fixed wireless access and to new IEEE 802.16e (Mobile WiMAX) standard with mobility support. Mobile WiMAX introduces the most significant feature that is support for handovers which can be considered as a basic requirement for mobile communication system. Since this standard support all type of data and applications like mobile Voice over Internet Protocol (VoIP), multimedia video stream (IPTV etc.) or multimedia gaming and other real time, non real time services, so the handover schemes must be fast and efficient should avoid any packet loss. This paper gives an overview of handover procedure and types of handover supported by mobile WiMAX. Keyword: Wi-MAX, handover, HHO, MDHO, FBSS
