Abstract
WirelessHART is the most widely applied standard in wireless sensor networks nowadays. However, it does not provide any dynamic routing mechanism, which is important for the reliability and robustness of the wireless network applications. In this paper, a collection tree protocol based, dynamic routing mechanism was proposed for WirelessHART network. The dynamic routing mechanism was evaluated through several simulation experiments in three aspects: time for generating the topology, link quality, and stability of network. Besides, the data transmission efficiency of this routing mechanism was analyzed. The simulation and evaluation results show that this mechanism can act as a dynamic routing mechanism for the TDMA-based wireless sensor network.

Summary
With the rapid progress of the WSN (wireless sensor network) [1, 2], wireless devices have been widely deployed in industrial environments to improve the efficiency of the industrial process. A dynamic routing strategy is proposed by evaluating and improving the CTP (collection tree protocol) [5, 6] to make it work as a solution to the dynamic routing mechanism for IWSN (industrial wireless sensor network). The evaluation of this mechanism is mainly concerned with three aspects: the time relating to generating topology, the link quality, and the stability of the topology. The rationality of this design is apparent
