In wireless networks, prediction methods are considered as efficient techniques to get information about the network capacity and availability. Delay and packet loss are two key QoS parameters for real time applications. Conventional MAC layer functions can only predict the link characteristics. In our paper, a cross layer design is deployed to get in-formation about the predicted end-to-end path quality and exploit this information to improve the behavior of the rout-ing protocol in Mobile Ad hoc Networks (MANETs). To achieve greater routing performance for applications with real time constraints, interaction between application layer and routing layer are needed. In our paper, a cross layer design between application layer and routing layer is defined to take into account the application QoS class. Application’ classes will be defined according to the user’s requirement thresholds defined by the ITU G-1010 recommendation. Our proposed routing protocol is suggested as an enhancement to the AOMDV: Ad hoc On-demand multipath Distance Vector protocol. A simulation study under NS2 will be conducted in this paper in order to validate our contribution.
