In wireless mesh network (WMN), multiple service providers (SPs) cancooperate to share resources (e.g., relay nodes and spectrum), to serve theircollective subscribed customers for better service. As a reward, SPs are ableto achieve more individual benefits, i.e., increased revenue or decreased cost,through efficient utilization of shared network resources. However, thiscooperation can be realized only if fair allocation of aggregated payoff, whichis the sum of the payoff of all the cooperative SPs, can be achieved. We firstformulate such cooperation as a coalitional game with transferable utility,specifically, a linear programming game, in which, each SP should obtain thefair share of the aggregated payoff. Then we study the problem of allocatingaggregated payoff which leads to stable service coalition of SPs in WMN basedon the concepts of dual payoff and Shapley value.
