摘　　要：为提高电力物联网信息感知层面的覆盖范围和可靠性,提出一种构建低压电力线与微功率无线通信跨层融合网络(CPW)的方法。首先建立CPW的统一介质访问控制(MAC)层模型,为实现CPW网络层的融合提供基础支持;然后提出一种结合布朗运动与局部收敛次数控制的改进蚁群算法,完成了CPW的组网过程;对CPW的子业务流进行分配,并提出业务分配中的误码率需求因子,实现了低压电力线与微功率无线通信网络的跨层融合。仿真结果表明,该跨层融合网络的通信链路服务质量优于电力线与无线双模或级联通信网络,用户可以根据不同业务设置相应的误码率需求因子,以兼顾通信链路质量与网络负载均衡,保障CPW的高效性和可靠性。In order to improve the coverage and reliability of the information perception layer of the Power Internet of Things,a method to establish the CPW(Cross layer fusion network of low voltage Power line and micro power Wireless communication)is proposed.Firstly,the unified MAC(Media Access Control)layer model of CPW is established to provide the basic support for the fusion of CPW network layer.Then,an improved ant colony algorithm controlled by Brownian motion and the number of local conver⁃gence is proposed to accomplish the networking process of CPW network.The sub-business of CPW network is allocated and the error rate requirement factor is proposed,which enables the cross-layer fusion of low voltage power line and micro power wireless communication networks.The simulative results show that the service quality of the communication link in the cross-layer fusion network is better than that of power line and wireless dual mode or cascade communication networks.Users can set corresponding error rate re⁃quirement factors according to different services to balance the quality of communication link and network load,so the efficiency and reliability of the CPW can be guaranteed.
