Abstract
A VoIP based call has stringent QoS requirements with respect to delay, jitter, loss, MOS and R-Factor. Various QoS mechanisms are being implemented to satisfy these requirements. These mechanisms must be adaptive under diverse network scenarios. Moreover such mechanisms must be implemented in proper sequence, otherwise they may conflict with each other. The objective of this paper is to address the problem of adaptive QoS maintenance and sequential execution of available QoS implementation mechanisms with respect to VoIP under varying network conditions. In this paper, we generalize this problem as a state-space problem and thereby solve it. Firstly, we map the problem of QoS optimization into state-space domain and then apply incremental heuristic search. We implement it under various network and user scenarios in a VoIP test-bed to optimize the performance. Finally, we discuss the advantages and uniqueness of our approach.
