Multimedia applications often require guaranteed quality of service (QoS) and resource reservation, which has raised a number of challenging technical issues for routing. We have proposed the QOLSR protocol, a QoS routing over OLSR protocol introducing metrics, such as bandwidth and delay, that are more appropriate than the hop distance. When using the QOLSR protocol, there are cases in which a source node continuously changes a flow's next hop in response to the change of available bandwidth on its path and cannot tell apart the traffic induced by itself from traffic generated by other nodes. The article describes a way to achieve QoS routing without using explicit reservation mechanisms and gives new distributed solutions to the oscillation and collision of flows. We can guarantee that the flows take the appropriate paths and avoid interferences with other existing flows. The performance of our distributed algorithm is extensively investigated by analyses, examples and simulations in both static and dynamic networks. Our results show that the gain achieved by our proposal represents an important improvement in mobile wireless ad hoc networks.
