Mapping of Received Signal Strength Indicator to QoE in VoIP applications over wlan

Abstract

This paper presents mapping of Received Signal Strength Indicator (RSSI) to Quality of Experience (QoE) in mobile devices for end to end VoIP communications over Wi-Fi. Through extensive experiments, relationships between RSSI and QoE were investigated and a mapping table from RSSI to QoE was created. The effectiveness of the proposed approach in terms of energy saving was also demonstrated by comparing it with conventional QoE monitoring approach.
