一种面向电力无线专网的虚拟资源优化分配机制

为了有效地保证智能电网中业务的隔离性和解决智能电网无线资源高效分配问题，该文借助网络虚拟化技术，提出一种面向电力无线虚拟专网的资源优化分配机制。首先，根据电力无线专网的特点，提出电力无线专网虚拟化系统模型，并通过建立网络模型抽象物理无线资源，实现资源共享；然后，综合网络成本、利润、业务隔离性约束、回程容量约束、QoS约束等因素，提出配用电接入网无线资源分配模型，且设计一种禁忌搜索的算法，在满足业务隔离和业务QoS要求的情况下，解决了配用电无线专网最优化虚拟资源分配。仿真实验表明，该文提出的基于禁忌搜索的电力无线虚拟专网资源优化分配机制，在满足业务QoS要求的情况下，降低了基站能耗，并提高了网络运行的经济效益。

Optimal Resource Allocation Mechanism for Electric Power Wireless Virtual Networks

To guarantee the isolation of the smart grid business and optimize the allocation of wireless resources, an optimal resource allocation mechanism for electric power wireless virtual networks is proposed. First, a virtualization system model according to the characteristics of electric power wireless network is proposed, and abstract physical wireless resource is built to realize resource sharing. Then, a wireless resource allocation model with several factors is designed, which are network cost, profit, service isolation constraint, backhaul bandwidth constraint, and QoS constraints. Finally, a tabu search algorithm based on these models is designed to allocate virtual resource to realize business isolation and QoS requirements. The simulation results show that, the proposed network model and optimal resources allocation mechanism can support QoS requirements, reduce the energy consumption of base stations, as well as improve the economic benefits of the network.
