Résumé

Cross layer design has been identified as a key mechanism to cope with instabilities caused by nodes mobility in wireless ad hoc networks. In this kind of networks, the fluctuations induced by the nodes movement result in channel variation that strongly affects the network layers functions such as scheduling, routing and flow control. To deal effectively with these fluctuations, we need to design a model for predicting the changes in the channel state and use them according to the networks needs. In this paper we propose an extension of the Dynamic Source Routing Protocol (DSR) which takes advantage of the link quality prediction in order to increase the probability that the selected paths will provide the required characteristics. The mobility of the nodes follows the GaussMarkov (GM) model, which was implemented by using the OPNET modeler tools. Furthermore, the DSR was modified in order to integrate the predicted link parameter and the simulated model performances are compared to the standard DSR.
