摘　　要：在智能制造背景下,为了提高无线网络的灵活性和能量使用效率,提出基于软件定义网络(SDN)的工业无线网络能量高效路由算法(SDERA)。基于SDN数据平面和控制平面分离的思想,构建了新型的工业无线网络模型,控制器根据应用需求、节点的剩余能量和负载等因素,计算全局最优路由策略并分发给交换节点,交换节点按照控制器的决策在不同的逻辑子网中转发数据包。当节点和链路质量信息以及应用需求发生变化时,控制器可以动态地调整路由策略,提高能量使用效率和网络性能。仿真实验结果表明,该路由算法有效地延长了网络的生存时间,提高了网络的能量使用效率。In order to improve the flexibility and energy-efficiency of industrial wireless network in the context of intelligent manufacturing,the software defined energy-efficient routing algorithm(SDERA)for industrial wireless network is devised in this paper.On the basis of the idea of software defined networking(SDN)which makes data plane and control plane separated,a novel industrial wireless network architecture is built.The global optimal routing strategy is calculated by the controller and distributed to the switching nodes according to the application requirements,residual energy and load of the nodes.The switching nodes retransmit packets in different logical subnets according to the decision of the controller.When quality information of the nodes and links,and application requirements change,the controller can dynamically adjust routing strategies to improve energy application efficiency optimize network performance.The simulation results show that SDERA meets the requirements of industrial data transmission and can effectively prolong the life cycle of the network.
