摘要

Assuring effective real-time audio communication over an ad-hoc network composed of mobile wireless nodes is an important new challenge in the wireless arena. In this paper, we propose a new playback algorithm denoted PAA (Periodic Adaptive Algorithm) which adapts periodically the playback latency based on the observation of network delay. The parameters of the algorithm have been chosen off-line with traces generated from several simulated scenarios. We show that PAA outperforms both IPolicy and E-Policy algorithms with respect to Mean Opinion Scores (MOS) performance indicator.
