Ajustement dynamique du délai de présentation des paquets pour le transport de la voix dans les réseaux ad hoc

Abstract : Errors treated in voice applications include lost packets arriving with long delays. Ad hoc networks introduce random delay variations in voice applications which require low delay and no jitter. To overcome this jitter and late lost packet, a dynamic playout delay adjustment algorithm is needed. As existing algorithms do not operate correctly in ad hoc networks characterized by mobility, a new algorithm is proposed. This algorithm takes advantage of RREQ control message of AODV reactive routing protocol (a typical event in ad hoc networks) to correctly deal with topology changes. The performance evaluation showed that it reacts correctly to the mobility effects. It outperforms the existing algorithms when considering interactivity, reliability and stability constraints.
