Handover Method Considering Power Consumption and Video Quality Satisfaction at the Mobile Node

In this paper, we propose a QoE-based handover method to consider mobile terminal power consumption and maintain experienced quality for a video streaming service like mobile IPTV. As a mobile terminal has dual mode interfaces with different power consumption and quality, a user can select an access network providing the satisfied quality and power efficiency. So, a mobile terminal needs the dynamic handover scheme between WLAN and alternative access network(3G) for better conditions. Through our simple experiment, existing RSSI-based handover schemes are not suitable to maintain the experienced quality of streaming multimedia service. Therefore we propose the QoE-based handover method through analysis of the relation between video experienced quality (MSSIM; Mean Structural Similarity Index).
