A MOS-based routing approach for wireless mesh networks

In this paper we propose a routing approach aimed at enhancing the quality of Voice-over-IP transmissions in multi-path Wireless Mesh Networks. The proposed approach executes a path switching based on the estimation of the Mean Opinion Score (MOS) for each available path of the mesh network. Performance results conducted through simulations show that the proposed approach, when compared to a random choice of the available paths, is highly effective in improving the performance of the VoIP calls in both static and dynamic scenarios.
