Abstract

Given a network in which the edge capacities and the commodities are owned by the players, a cooperative multicommodity flow (MCF) game (N ,v ) can be defined such that v (S ), the value of a sub-coalition S , is the maximum profit achievable within S by shipping its commodities through the sub-network owned by its members. In this paper, we study MCF games under a partially decentralized setting where the players make their own routing and resource exchange decisions given a set of capacity prices determined by a central authority.
