A solution for QoS support in wireless ad hoc networks

National audienceMore and more applications supported by MANETs require Quality of Service (QoS). Much research has been done to date on QoS in ad-hoc networks. In this paper, we present our solution to provide QoS support through different QoS components. We show that the scheduling component does not suffice to satisfy QoS flow requirements because of radio interferences. Interferences could decrease the application throughputs. This can be a real problem for applications that need bandwidth guarantees. To offer guarantees to QoS flows, we propose a solution made up of five QoS components
