摘　　要：现有无线通信技术和无线传感器网络中的路由协议无法完全满足工业现场应用需求。为了解决工业无线网络中数据通信的确定性、可靠性和实时性等问题,提出了一种基于确定性调度与链路质量的前k优路径路由算法,根据IEEE802.15.4的工业无线网络DL子网的特点,选取传输延时和链路质量作为路径选择的评价标准。通过算法的实现、仿真分析以及测试,结果表明:该算法有效的改善了通信过程中的确定性、高可靠性等问题,并降低了网络开销、节省了网络资源。Existing routing protocols of wireless sensor network can not effectively meet the application requirements of industrial wireless communication network. In order to solve the problems of determinability, reliability and real-time capability,a pre-k optimal path algorithm based on deterministic scheduling and link quality indicator is proposed,which selects transmission delay and link quality indicator as the routing criteria according to the characteristics of DL subnet in industrial wireless network based on IEEE 802.15.4. The algorithm was implemented;simulation analysis and testing were carried out. Simulation and test results show that the algorithm is applicable to industrial wireless network;it can effectively improve the determinability and reliability,reduce network overhead and save network resource.
