Abstract
Radio interferences and low capacity resources in ad-hoc wireless networks make more complex the quality of service (QoS) support. We propose a solution taking into account radio interferences in mobile ad-hoc networks routing and providing an optimized flooding based on multipoint relays. This solution is based on a modified version of the OLSR routing protocol that considers bandwidth requests and interferences in route selection while providing a very efficient flooding. A comparative performance evaluation based on NS simulations shows that despite the overhead due to QoS support, this solution outperforms classical OLSR in terms of maximum number of acceptable flows, bandwidth amount granted to a flow and route stability. Moreover, the efficiency of the optimized flooding is equal to that provided by the native version of OLSR.
