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 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 that we compare and evaluate in the OMNet++ simulation environment.
