摘要 无线HART(Highway Addressable Remote Transducer)是当前工业无线传感器网络中应用最为广泛的协议,但无线HART没有提供动态路由机制以满足对工业无线网络应用至关重要的稳定性和鲁棒性。该文在无线HART协议基础上,提出一个基于收集树协议的可应用于工业无线传感器网络的动态路由机制。它占用时分多址(TDMA)超帧中的前几个时间片来产生和维护网络拓扑。通过仿真实验从3个方面对该动态路由机制进行了评估:拓扑生成时间,链路质量及网络拓扑的稳定性。仿真和评估结果表明该动态路由机制可以在基于TDMA的工业无线传感器网络中应用。 Wireless Highway Addressable Remote Transducer (HART) is the most widely applied standar(1 to industrial wireless sensor networks nowadays. However, it does not provide any dynamic routing mechanism, which is important for the reliability and robustness of the industrial wireless network applications. In this paper, a collection tree protocol based dynamic routing mechanism is proposed for industrial wireless sensor networks in the base of wireless HART protocol. This mechanism generates and maintains the network topology through occupying several time slots in the Time Division Multiple Address (TDMA) super frame. The dynamic routing mechanism is evaluated through several simulation experiments in three aspects: time for generating the topology, link quality and stability of network. The simulation and evaluation results show that this mechanism can act as a dynamic routing mechanism for the TDMA-based industrial wireless sensor networks.
