Abstract: In this work we select AODV, OLSR and HWMP routing protocols and focus on how they can affect the Quality of user Experience (QoE) with respect to VoIP on a wireless backbone. We calculated QoE by using a reviewed version of the E-model. Since that parameter is strongly correlated with some stochastic network variables it presents stochastic behaviour too. So, we discuss important issues needed to estimate QoE based parameters in a trusty way. Results showed that the average QoE kept acceptable only under AODV routing as the number of VoIP traffic was increased in the network.
