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 is to propose improvement handover scheme for mobile WIMAX. This scheme depends on the velocity factor of mobile station and it aims to reduce handover delay time and enhance the network resource utilization. The simulation result shows that the proposed scheme is more than 90 % efficient.
