Thaalbi M., Tabbane N. (2010) Vertical Handover between WiFi Network and WiMAX Network According to IEEE 802.21 Standard. In: Elleithy K., Sobh T., Iskander M., Kapila V., Karim M., Mahmood A. (eds) Technological Developments in Networking, Education and Automation. Springer, Dordrecht
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.
