QoS驱动的电力通信网效用最大化资源分配机制

智能电网业务的多样性和对QoS的不同需求，是电力通信网资源分配时急需解决的问题.网络虚拟化是网络转型的关键技术，在保障业务QoS和提高资源利用率方面具有非常大的优势.本文基于网络虚拟化技术，对QoS驱动的电力通信网资源分配问题进行了形式化的描述，提出了基于三方博弈的两阶段资源分配模型.基于此模型，提出一种QoS驱动的电力通信网效用最大化的资源分配机制.通过对提出的资源分配机制的分配策略性能分析，证明了本文提出的资源分配机制满足占优策略激励兼容特性，并且可以实现系统利润最大化的目标.通过仿真实验，验证了本文提出的机制能够实现电力通信网的效用最大化，提高了电力通信网的资源利用率.

QoS-Driven Utility Maximizing Resource Allocation Mechanism for Power Communication Network

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.
