| Abstract: | This paper discusses a management architecture for devices operating in heterogeneous environments, that enables access network
selection through terminal-controlled, preference-based mechanisms. In this domain two problems are identified, mathematically
formulated and solved: Intelligent Access Selection (IAS) and Modelling and Adaptation to User Preferences (MAUP). Their objective
is to compute the optimal allocation of services to access networks and quality levels, and to dynamically determine user
preferences according to the usage context, respectively. A greedy algorithm is proposed for the IAS problem, while the MAUP
problem is handled through the construction of a Bayesian network that allows inference and learning of profile and usage
patterns. Extensive simulation results of the proposed methods and algorithms are also presented.
