Abstract. Radio resource management and QoS provision in Mobile
Ad hoc NETworks (MANETs) require the cooperation among different
nodes and the design of distributed control mechanisms, imposed by the
self-configuring and dynamic nature of these networks. In this context,
in order to solve the tradeoff between QoS provision and an efficient
resource utilization, a distributed admission control is required. This
paper presents an adaptive admission procedure based on a cross-layer
QoS Routing supported by an efficient end-to-end available bandwidth
estimation. The proposed scheme has been designed to perform a flexible
parameters configuration that allows to adapt the system response to the
observed grade of mobility in the environment. The performance evaluation
has shown the capability of the proposal to guarantee a soft-QoS
provision thanks to a flexible resource management adapted to different
