Team decision approach for decentralized network selection of mobile clients

We consider a network selection problem for a group of mobile clients that operate in a heterogeneous wireless access network environment and that are equipped with multiple access network interfaces. The involved networks cooperate in order to improve their own, and the mobile clients´ performance. We formulate the problem as a team decision problem. In this formulation, several decision variables are involved and these decisions are made by several decision makers with access to different information but contributing to a common goal. The novelty of the proposed approach is that the network selection is done in a decentralized manner with only limited information available to decision makers. We present two decentralized algorithms to this problem, which we compare and evaluate in the OMNet++ simulation environment.
