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,
