摘　　要：基于IEEE-802.15.4标准的WIA-PA网络中的虚拟通信关系(Virtual Communication Relationships,VCR),分析了无线网络中的最小跳数路由算法与节能型路由算法,讨论了这两种算法的优缺点。结合二者的优点以及WIA-PA网络中VCR的特点,提出了一种基于VCR的路由算法。仿真结果表明,所提算法能根据不同的VCR采用恰当的路由,实现了管理报文转发低延迟、数据报文转发低能耗,满足了工业无线应用的实际需求。Based on the IEEE-802.15.4 standard and WIA-PA networks with VCR in it,the minimum hop routing algorithm and energy-efficient routing algorithm in wireless networks were introduced.The advantages and disadvantages of the two algorithms were analyzed and compared.By combining the minimum hop routing algorithm and routing algorithm for energy-saving advantages as well as VCR in the WIA-PA network,a routing algorithm based on the VCR was designed and simulated.Simulation results show that the novel routing algorithm based on VCR with combing the two traditional routing algorithms is efficient.By comparing the WIA-PA VCR application with different routing algorithms,it achieves lower delay management data packet forwarding and energy consumption of data packets transmitting,and is more suitable for the WIA-PA network applications.
