Research on Dynamic Routing Mechanisms in Wireless Sensor Networks

الملخص EN

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.
