Wireless Mesh Network (WMN) is an emerging technology that is gaining importance among traditional wireless communication scenarios. Wireless Mesh Networks are becoming a popular way of offering end-to-end services, such as Voice over IP (VoIP) and Video on Demand (VOD), in an inexpensive, practical, and fast manner. However, those applications require a minimum network performance level in order to provide an acceptable Quality of Experience (QoE) level to users. In this paper, we present a QoE based approach, which analyzes key QoS parameters like delay, jitter, and packet loss in a mesh network executing the Better Approach To Mobile Ad hoc Network (BATMAN) proactive routing protocol. The proposed mechanism evaluates the actual QoE level from the point of view of each mesh node taking into account the calculated QoS parameters, and then proposes a response in case of QoE degradation as reducing the node broadcasting rate.
