摘　　要：针对无线传感器网络满足微电网数据通信规范性能指标要求问题,探索了一种微电网数据传输无线传感器网络协议栈跨层协作服务质量控制方法。通过分析影响微电网无线传感器网络数据传输的性能指标的主要因素,构造了包含10类概念顶点集合的模糊认知图,以数学模型方式表达无线通信网络中的主要参量之间的因果关系,建立了微电网数据传输无线传感器网络实时性和可靠性服务质量对应的状态空间模型。依据模糊认知图的概念顶点属性模糊推理机制,探讨了一种微电网数据传输无线传感器网络跨层协作服务质量的模糊控制方法,给出了以满足微电网数据通信规范性能指标要求的3种不同状况下的网络参数调节方法和路由路径动态调整策略。通过对微电网数据传输中不同数据产生率情况下的网络性能分析仿真实验分析,结果表明,本方法可为基于无线传感器网络的微电网数据通信提供更有效的QoS保障。In order to satisfy the performance requirements of Micro-grid communication, a cross-layer control for improving the quality of service(QoS) of wireless sensor networks(WSNs) is researched. By analyzing the main factors affecting the micro-grid data communication in the WSNs, a fuzzy cognitive map(FCM) model containing ten types of conceptual vertices is built. Then, the expression of the causality is built, including the relation among the main parameters in the wireless communication networks, and the state-space model of the real-time and reliability in the WSNs for micro-grid communication. According to the fuzzy inference mechanism of conceptual vertices in FCM, a cross-layer fuzzy control method of WSNs for micro-grid data communication is investigated. Afterwards, the adjustment method of network parameters and the dynamic adjustment strategy of routing path are researched. The simulation results in different data rate scenarios show that the method proposed can provide more effective QoS for WSNs of micro-grid communication.
