WiMAX (Worldwide interoperability for Microwave Access), it is a technology that is based on IEEE802.16 standard for Broadband Wireless Access (BWA). The mobile WiMAX or the 802.16e-2005 launch the incredible latest feature, mobility to support for handoffs, that is essential for mobile communication system. Hard handoff is mandatory in mobile WiMAX and the two optional soft handoff methods are known as macro diversity handover and fast base station switching. During hard handover, the data transmission should be suspend and makes handover delay in mobile communication. Due to handover delay, there is severe degradation in system performance when implemented in real-time applications like VoIP (Voice over IP). The existing standard considers only the received signal strength that decides when handover occur.
