Optimal Decision Making Distribution in Composite Networks

This paper presents a policy-based radio resource management model for decision sharing between the network and the mobile terminals in composite networks. One of the key issues discussed in this paper is the distribution of RRM decision making between the network and the mobile terminal. IEEE P1900.4 standard project proposes a policy-based radio resource usage scheme where the network orients the mobile terminals decisions by sending rules and constraints. Mobile terminals choose the most appropriate action to their own QoS objectives, within the action set allowed by the network. We propose a joint RRM framework based on this standard project and we discuss both policies definition on the network side and decision making on the mobile terminal side. We propose a model where policies are chosen automatically according to the variations of the environment conditions and the operator strategy. On the mobile terminal side, we propose to introduce a time constraint imposed by the network for policy execution in order to coordinate the resulting terminals´ actions execution over time. Moreover, as final decisions are made by MTs in a distributed way, we discuss the modeling of this problem using cooperative and non cooperative games approaches.
