摘要:

节点能量受限与移动性及更加个性化的服务要求,使自组织网络对定制化路由需求迫切。基于软件定义网络(SDN)的核心原理,首先分析 SDN 下自组织网络控制架构和路由设计的全新思路。其次建立分层次路由模型,提出基于服务路径的路由关键节点和关键链路集中式选择问题并设计其算法,通过基于服务特征的节点映射,以网络效能最大化为目标将用户定制的服务嵌入物理网络中。最后验证了基于 SDN 的自组织网络路由在功能、性能和网络整体效能方面的优势。实验证明,网络节点耗能更均衡且网络整体效用比传统方法提高近14%。

关键词: 软件定义网络, 自组织网络, 服务路径, 定制化路由, 网络效能

Abstract:

Node energy-limited and mobility,indeed,requirement of customized service,made Ad Hoc press for customization Routing.Based on the core principle of software defined networking (SDN),the control framework and the design of routing creation bran-new approach about Ad Hoc based SDN was analyzed firstly.Secondly,the hierarchical routing model was established,and the problem of routing key nodes and key link centralized selection based on service path was proposed and its algorithm was designed,which could embed customize service into physical networks via nodes mapping based network performance maximization.Finally,it corroborate the advantage of routing implement via SDN in function,performance and the whole networks utilization.Experiments show that the energy consumption of network nodes is more balanced and the overall utilization of the network is nearly 14% higher than the traditional method.

Key words: software defined networking, Ad Hoc, service path, customization routing, network utilization
