Abstract
Voice over IP applications require playout buffer at the receiver side to smooth network delay variations. Existing algorithms for dynamic playout adjustment used in Internet do not operate correctly in wireless ad hoc networks because they estimate end-to-end delay based on set of previous received audio packets. Mobility in ad hoc networks leads to topology changing and estimate based on past history is not appropriate. In this paper, we propose a new algorithm for playout delay adjustment based on Route Request AODV control messages to provide more accurate delay estimation. The performance evaluation shows that this algorithm outperforms existing playout delay adjustment algorithms. Performance criteria are the loss late percentage (reliability criterion), averaged playout delay (interactivity criterion) and playout delay variation (stability criterion).
