Résumé

Ad hoc wireless networks have enormous commercial and military potential because of their self-organizing capacity and mobility support. However, some specificities of these networks such as radio interferences and limited resources make more complex the quality of service (QoS) support. Indeed, on the one hand, the bandwidth offered to users is strongly affected by radio interferences. On the other hand, flooding information in such a network must be optimizedin order to save resources. Therefore, we propose in this paper, a solution taking into account radio interferences in mobile ad hoc network routing and optimizing flooding. This solution is based on a modified version of the OLSR routing protocol that considers bandwidth requests and radio interferences in the route selection process while providing a very efficient flooding.A comparative performance evaluation based on NS simulations shows that despite the overhead due to QoS management, this solution outperforms classical OLSR in terms of QoS perceived by the users (e.g. bandwidth amount granted to a flow and delivery rate). The efficiency of the optimized flooding is equal to that provided by the native version of OLSR
