Q-SWiM: QoE-based routing algorithm for SVC video streaming over wireless mesh networks

This paper presents a QoE-based multipath routing algorithm for scalable video coding (SVC) over multichannel wireless mesh networks (WMN). The availability and quality of links in WMN significantly depends on not only the positions of neighbors but also the interference between links. In video streaming, the quality perceived by the users is the key to success. Consequently, enhancing experience of users and network utilization in these networks is an interesting challenge. In this paper, we utilize multicommodity model to formulate the problem of streaming SVC video over multichannel WMN. Then, we propose a heuristic algorithm to speed up searching solution procedure. Simulation results demonstrate that the proposed algorithm can obtain a near-optimal solution within a short calculation time.
