The input metrics needed by the suggested multicriteria decision-making module include the characteristics of the access network or radio channel, the characteristics of the object, application requirements, users’ QoS preferences and the energy constraints and user sensitivity to some bands that could interfere with medical equipment in an e-health context, for example. All this information is stored in the databases. We distinguish types of input parameters: the measured, predicted and static parameters. The detection module for the intelligent radio and the monitoring module in the M-RAN context provide measured parameters. The prediction module will be responsible for predicting channel availability and the average duration for which they are available. The static parameters include fixed characteristics of the network or radio channel, user preferences and application requirements. The application needs we retain are linked to the QoS required by the application, such as the minimal bandwidth, the maximum delay allowed, the maximum jitter tolerated m and the maximum packet loss rate tolerated.
