QoE and QoS in wireless mesh networks

The increasing demand of multimedia applications requires a new behavior of routing protocols for wireless mesh networks (WMNs). It is necessary to support the minimum requirements for quality of service (QoS), but WMNs also need to support the minimum requirements for quality of experience (QoE). This paper is an additional analysis of the proposed routing protocol OLSR-DC, from a perspective of the network (QoS) and from a perspective of the user (QoE). The simulations were performed to demonstrate the performance of OLSR-DC compared against original OLSR and its ETX and MD versions considering different performance evaluation metrics and the quality of the video received by the user.
