Mobile WiMAX is a wireless technology based on IEEE802.16e for broadband wireless access. Mobile WiMAX introduces the most significant new feature, mobility to support for handovers, which can be considered as a basic requirement for mobile communication system. The mandatory handoff method is hard handoff for mobile WiMAX and other two optional soft handoff methods are macro diversity handoff and fast base station switching handoff method. Hand over delay generates during data transmission but handover delay should be less than 50ms over real time applications such as Voice Over Internet Protocol (VOIP). The existing draft standard considers only the received signal strength when deciding handover. The mobility improvement handover scheme that depends upon the velocity factor has been taken into consideration in this paper. The proposed scenario has been implemented using QualNet network simulator which has led to less handover time.
