Mobile ad hoc networks (MANETs) are nowadays being used much more than some years ago. One of the major reasons is the increasing number of devices that have risen lately capable of forming part of such networks. This situation makes feasible the development of new services. Especially, video-streaming is one of the most successful services demanded by the customers. In this paper we propose a QoS-aware multipath DSR-based (dynamic source routing) routing protocol which helps to improve the reliability of the connections while balancing the load and decreasing the end-to-end delay. Several multipath routing designs have been evaluated seeking to get better global performance of the network. Besides, we propose a QoS-aware architecture that includes a cross-layer scheme in which a network layer scheduler manages different priority traffics and operates according to the IEEE 802.11e MAC (medium access control) layer. Extensive simulations have been carried out to show the benefits of our scheme in providing different levels of QoS, including user-level QoS parameters
