This paper proposed a resource allocation scheme based on the coalitional game. First, it used an admission control mechanism to provide services of mobile applications to the users given the available long-term reserved resources in a pool. And it introduced an optimization formulation to obtain the optimal decision of admission control. Then, for a given coalition of service providers, the revenue obtained from utilizing the resource pool had to be game shared among the service providers. It developed a coalitional game model for sharing the revenue. The simulation results show that the proposed method is effective, which can obtain the optimal strategies of service providers on capacity expansion such that their profits are maximized.

Recently, the hybrid wireless-optical broadband network integrating optical backbone networks, passive optical networks, and wireless access networks have been proposed to provide the high-bandwidth, low-cost, and ubiquitous communication connections. This paper considered the design of network coding-based multicast applications in such networks with the objective of maximizing the total network utility and minimizing the deployment cost. The problem was formulated as a mixed integer nonlinear programming problem and the exact solution is prohibitively complex. In order to make the problem more tractable, it developed a two-step optimization procedure that iteratively selected the optical network unit and gateways for the multicast sessions. During each iteration, it solved two subproblems a network coding design problem for the optical network and a user assignment and bandwidth allocation problem for the wireless network. The former was solved in a distributed way based on the Lagrangian-dual decomposition; the latter was solved based on the generalized bender decomposition. Simulation results illustrate the effectiveness of the proposed solutions. [ABSTRACT FROM AUTHOR]
