【摘要】：为了解决无线传感器网络(WSNs)的规模大、分布广而带宽有限与智能配电网对通信数据实时性和可靠性有上确界之间的矛盾,提出了一种基于最小流量的无线传感器网络路由通信模型。以无线传感器网络链路节点中接收到数据与发送出的数据之间的流量平衡为切入点并结合无线传感器网的通信约束条件以及配电网数据传输的实时性需求,建立了基于最小流量的智能配电网无线传感器网络的路由通信模型。利用庞特里雅金极值的方法构建出所设计智能配电网无线传感器网络通信模型的哈密尔顿函数。利用极值存在的唯一性,从必要性出发判断出无线传感器节点是否在最优路链路径上。并给出了最优控制模型的求解过程。最后对采取所提出的通信模型的延时时间、网络能量消耗、数据传输能力以及数据传输的错误率对比测试。结果表明,所提出的通信模型完全能够满足智能配电网通信需求。
[Abstract]:In order to solve the contradiction between the large scale, wide distribution and limited bandwidth of wireless sensor network (WSNs) and the real time and reliability of communication data in smart distribution network, This paper presents a routing communication model for wireless sensor networks based on minimum traffic. Taking the traffic balance between the received data and the transmitted data in the link node of the wireless sensor network as the breakthrough point, combining the communication constraints of the wireless sensor network and the real-time demand of the distribution network data transmission, The routing communication model of smart distribution network wireless sensor network based on minimum flow is established. The Hamiltonian function of the wireless sensor network communication model of smart distribution network is constructed by using the Ponrijagin extremum method. Based on the uniqueness of the existence of extremum, it is necessary to determine whether the wireless sensor node is in the optimal path. The process of solving the optimal control model is given. Finally, the delay time, network energy consumption, data transmission capability and error rate of the proposed communication model are compared and tested. The results show that the proposed communication model can fully meet the communication needs of smart distribution network.
