Flexible resources reservation scheme for ad hoc networks

Ad hoc networks (AHNs) include mobile nodes with limited communication resources on which the path selection is usually made according to a best effort strategy. Today, AHNs are facing a new challenge: a resources reservation mechanism oriented quality of service. The importance of this challenge makes this issue focused by several researchers. In this paper we propose a flexible QoS reservation mechanism for AHNs, called F_QSRR. In our proposition, we consider a novel scheme for the resources allocation allowing an optimistic and pessimist behaviour to the applications. The advantages of this proposition are shown thanks to some simulation results that are detailed in the end of this paper.
