Abstract

Mobile ad hoc wireless networks (MANETs) have enormous commercial and military potential because of their self-organizing capacity and their mobility support. More and more applications such as multimedia applications, video games, and voice over IP have quality of service (QoS) requirements: minimum bandwidth, end-to-end delay and jitter. However, some specificities of MANETs such as radio interferences and low capacity resources make more complex the QoS support. In this paper, we propose an efficient solution based on the OLSR routing protocol. This solution provides the shortest path offering the requested bandwidth. Performance evaluation shows that the QoS perceived by the users (e.g. throughput and delivery rate) is highly improved. Resource utilisation is good because of optimized flooding and load sharing between several paths.
