Multi-Path OLSR is an extension of the single path routing protocol OLSR. The QoS has been demonstrated in simulation and testbed. In this paper, we attempt to confirm those results at the application layer specially for critical applications as video services over wireless networks. The standard H264/SVC is chosen for its enormous potential in video delivery in lossy networks. Still vulnerable to packet losses, we combine the scalable source coding to an Unequal Error Protection (UEP) scheme in order to improve a simple Quality of Experience (QoE) measurements i.e PSNR. In a new simulation framework called SVCEval, the combination of path diversity and scalable protection insures a significant 2 dB gain in QoE for sensitive contents and mobile scenarios in comparison with just MP-OLSR. Within the same context, single path strategy delivers non acceptable video services as soon as nodes are mobile.
