User mobility management is one of the important components of mobile multimedia environments. That is, mobile users should obtain network resources after handoff for seamless service supports. So, an adaptive handoff scheme has been proposed to minimize the connection dropping probability for handoff connections. This paper shows the comparative performance analysis for the adaptive QoS handoff mechanism with existing solutions such as Non-Priority Scheme (NPS) and Guard-Channel Scheme (GCS). It has been shown from the performance evaluations that the adaptive QoS mechanism provides lower dropping and blocking probability than existing schemes.
