IEEE 802.21 is one of the emerged standards designed to build handover between heterogeneous technologies while optimizing session continuity. In this paper we provide a performance evaluation of the vertical handover between WiFi and WiMAX using IEEE802.21 for different traffic flows: VoIP, video streaming and FTP. The performance metrics used for this evaluation include throughput, end-to-end delay and packet loss rate. The performance evaluation is done using the Network Simulator NS2.
