Analyzing the Performance of WiMAX Zone Handover in the Presence of Relay Node Qualnet6.1
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).
