N2 - This paper evaluates the performance of IEEE 802.21 Media Independent Handover (MIH) framework through test-bed experiments conducted on a wireless platform that allows seamless handoff across heterogeneous radio access technology networks of mobile terminals with on-going video sessions. The scope of the study is to evaluate how MIH performs under different handover triggering techniques and to monitor the impact at both packet loss and perceived video quality due to vertical handover. We propose a handover decision policy as part of the MIH framework, which is based on parameters from the physical, network and application layers, gathered from MIH capable mobile terminals and MIH controlled radio access networks. Real testbed experiments demonstrate that triggering from application layer can maintain and optimize QoS better than the network layer triggering.
