Abstract
We propose a simulation-based approach to quality-of-service (QoS) improvement of multimedia streaming over wireless LANs. Since multimedia applications have stringent real time constraints, transmission schemes which rely on massive use of redundancy are not viable options. We present a portable simulation framework consisting of re-configurable software components. We build a simulation model which reflects the peculiarities of the MPEG-2 coding technique and streaming process by specializing the objects of the framework. We propose a set of strategies, which improve the QoS of the transmission, while limiting the amount of redundancy used. Finally, we conduct a quality and cost analysis of the proposed alternatives via detailed simulation of a case study system. © 2003 Elsevier B.V.
