Abstract
Handover (HO) mechanism in mobile Wimax is one of the critical operations.It takes place when a mobile station (MS) moves from a serving base station (SBS) to another base station (BS).However, the handover schemes are adopted in mobile Wimax and hard handover is defined as mandatory.Since the data transmission should pause during handover process, it causes delay in mobile communication.The handover delay makes service degradation in system performance when implemented in real-time application such as Voice over IP (VoIP) and Internet protocol Television (IPTV).This paper propose an improvement in handover scheme for mobile WiMAX.which addresses the heterogeneous network .We evaluated the performance metrics such as handover latency and data loss performance for different WiMAX cell handover.In addition, we as also modified our simulation model of Mobile service for the analyzing the performance of WiMAX zone handover in Qualnet
