【摘要】：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、Qo S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Qo S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Qo S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。
[Abstract]:In order to effectively guarantee the isolation of service in smart grid and solve the problem of efficient allocation of wireless resources in smart grid, this paper makes use of network virtualization technology. This paper proposes an optimal resource allocation mechanism for power wireless virtual private network. Firstly, according to the characteristics of power wireless private network, a model of power wireless private network virtualization system is proposed. And through establishing the network model to abstract the physical wireless resources, the resource sharing can be realized. Then, considering the network cost, profit, service isolation constraints, return capacity constraints and QoS constraints, a distribution access network wireless resource allocation model is proposed, and a Tabu search algorithm is designed. In the case of service isolation and QoS requirements, the optimal virtual resource allocation of distribution power wireless private network is solved. In this paper, a Tabu search based optimal allocation mechanism for power wireless virtual private network resources is proposed, which can reduce the base station energy consumption and improve the economic benefit of the network operation under the condition of satisfying the QoS requirements of the service.
