Abstract: Worldwide interoperability for microwave access or WiMAX is considered as a promising technology for providing wireless connectivity. This is because it has a large coverage area, high-speed data rates, and low cost of deployment. Handover management for voice over internet protocol (VoIP) service is one of the recent issues that face WiMAX technologies that require special configurations. In this paper, we study the performance of the WiMAX network during the handover of a mobile node from the base station to another. It is known that when the node moves away from its home agent it can receive packets but the sending process decrease with the handover appears. In this paper, we will also recover this problem using the OPNET simulator shown the network performance in traffic send and receive for a VoIP application.
Keywords: WiMAX; worldwide interoperability for microwave access; VoIP service; handover; OPNET simulator; normal configuration; traffic configuration; low cost; traffic performance; high data rates.
