Abstract:The diversity of Smart Grid services and the different QoS requirements are the urgent problems to be solved for allocating resources of power communication network. Network virtualization is the key technology of network transformation, which has a great advantage in ensuring QoS and improving resource utilization. Based on network virtualization technology, this paper describes the problem of QoS-driven resource allocation for power communication network and proposes a two-stage resource allocation model based on tripartite game, and then QoS-Driven Utility Maximizing Resource Allocation Mechanism (QDUMRAM) is proposed. It is proved that the QDUMRAM satisfies the compatibility of the dominant strategy and can achieve the goal of maximizing the system profit. Simulation results show that the QDUMRAM can maximize the utility and improve the resource utilization rate for the power communication network.
